Graphdiyne is a novel carbon material. Similar to graphene, graphdiyne consists of a single-layer network structure composed of $\mathsf { s p } ^ { 2 }$ and $\mathsf { s p }$ hybridized carbon, with layers connected by van der Waals forces. Because $\mathsf { s p } ^ { 2 }$ hybridized carbon and sp hybridized carbon can have various arrangements, graphdiyne can have multiple structures. In one type of graphdiyne, each $\mathsf { C } ( \mathsf { s p } ^ { 2 } ) $ is connected to three $\mathsf { C } ( \mathsf { s p } ) $, and each $\mathsf { C } ( \mathsf { s p } ) $ is connected to one $\mathsf { C } ( \mathsf { s p } ) $ and one $\mathsf { C } ( \mathsf { s p } ^ { 2 } ) $ respectively, which we temporarily name graphdiyne $A$ here; in another type of graphdiyne, each $\mathsf { C } ( \mathsf { s p } ^ { 2 } ) $ is connected to two $\mathsf { C } ( \mathsf { s p } ) $ and one $\mathsf { C } ( \mathsf { s p } ^ { 2 } ) $ respectively, and each $\mathsf { C } ( \mathsf { s p } ) $ is connected to one $\mathsf { C } ( \mathsf { s p } ) $ and one $\mathsf { C } ( \mathsf { s p } ^ { 2 } ) $ respectively, which we temporarily name graphdiyne $B$ here; in addition, there is a graphdiyne structure consisting of a network structure composed of $[ \mathsf { C } ( \mathsf { s p } ^ { 2 } ) \mathsf { C } ( \mathsf { s p } ) \mathsf { C } ( \mathsf { s p } ) \mathsf { C } ( \mathsf { s p } ^ { 2 } ) ]$, but containing a benzene ring structure, which we temporarily name graphdiyne $C$ here.

The graphdiyne $C$ variant, graphdiynes, can be synthesized on any substrate using hexaethynylbenzene as a monomer. The method involves wrapping the substrate material in a metal mesh and immersing it in an acetone solution containing hexaethynylbenzene in pyridine and tetramethylethylenediamine, which can induce a Glaser-Hay alkyne coupling reaction on the substrate to obtain the grown graphdiynes.

Based on the above background information, which of the following statements is incorrect ( )?
石墨炔是一种新型的碳材料。与石墨烯类似，石墨炔通过 $\mathsf { s p } ^ { 2 }$ 和 $\mathsf { s p }$杂化的碳构成单层的网络结构层与层之间通过范德华力连接。因 $\mathsf { s p } ^ { 2 }$ 杂化的碳和sp杂化的碳可以有多种排列方式，所以石墨炔可以有多种结构。其中一种石墨炔，每个$\mathsf { C } ( \mathsf { s p } ^ { 2 } ) $与三个$\mathsf { C } ( \mathsf { s p } ) $连接，每个$\mathsf { C } ( \mathsf { s p } ) $分别与一个$\mathsf { C } ( \mathsf { s p } ) $和一个$\mathsf { C } ( \mathsf { s p } ^ { 2 } ) $连接，我们在此暂时命名为石墨炔$A$；另一种石墨炔，每个$\mathsf { C } ( \mathsf { s p } ^ { 2 } ) $分别与两个$\mathsf { C } ( \mathsf { s p } ) $和一个$\mathsf { C } ( \mathsf { s p } ^ { 2 } ) $连接，每个$\mathsf { C } ( \mathsf { s p } ) $分别与一个$\mathsf { C } ( \mathsf { s p } ) $和一个$\mathsf { C } ( \mathsf { s p } ^ { 2 } ) $连接，我们在此暂时命名为石墨炔$B$；此外还有一种石墨炔结构是由 $[ \mathsf { C } ( \mathsf { s p } ^ { 2 } ) \mathsf { C } ( \mathsf { s p } ) \mathsf { C } ( \mathsf { s p } ) \mathsf { C } ( \mathsf { s p } ^ { 2 } ) ]$ 组成的网络结构，但含有苯环的结构，我们在此暂时命名为石墨炔$C$。

结合以上背景资料，以下说法错误的是（ ）。
Graphdiyne $A$ has six $\mathsf { s p }$ hybridized carbons in the primitive cell.
Metal mesh elements have two stable ionic valence states.
Graphdiyne $C$ can be synthesized from monomers containing three bromine atoms.
Graphdiyne $A$ can be synthesized from a monomer containing two bromine atoms, and this monomer cannot have cis-trans isomers.
Graphene-yne $A$ and graphene-yne $C$ have a ratio of 2:3 in the number of carbon atoms contained in their primitive unit cells.
Graphdiyne $C$ adopts an ABAB layered stacking (alternating concentric large and small rings), and after sodium ions are intercalated into the interlayer, it forms a NaC composition (i.e., Na:C=1:1). If the polygons in its top view represent carbon skeleton pores (carbon atoms are not drawn), and the dots represent sodium ions, then the sodium ions are located at the center of the regular hexagon formed by the overlapping projection of layer A and layer B, with one sodium ion per hexagon.

A: Graphdiyne $A$ is an 18-membered ring arrangement of hexagons composed of $[ \mathsf { C } ( \mathsf { s p } ^ { 2 } ) \mathsf { C } ( \mathsf { s p } ) \mathsf { C } ( \mathsf { s p } ) \mathsf { C } ( \mathsf { s p } ^ { 2 } ) ]$ cycles. According to the definition and division principles of a proper unit cell, its proper unit cell is a rhombus containing 8 carbon atoms [a rhombus formed by connecting the centers of four 18-membered rings in adjacent rows (taking two 18-membered rings each from the upper and lower rows)], which contains 6 $\mathsf { s p }$ hybridized carbons and 2 $\mathsf { s p2 }$ hybridized carbons.

B: The copper-catalyzed cross-coupling reaction of terminal alkynes (Glaser-Hay reaction) is a fundamental reaction in organic chemistry. It is inferred that the metal mesh is a copper mesh, and Cu(py)2+ can migrate to the substrate for adsorption, and then the catalytic coupling reaction occurs on the substrate surface. The stable valence states of copper ions include +1 and +2.

F. ABAB stacking means that the rings of adjacent layers (A and B) are not aligned, but the cocentric rings of different sizes are staggered, so the polygon projections of layers A and B should be staggered in the top view. The description "sodium ions are filled in the interlayer and the position of sodium ions in each layer is the same" indicates that sodium ions are located between the two layers. If the sodium ions are located in the center of the overlapping area, the overlapping area may not be centered after the AB layers are misaligned. "Sodium ions are located in the center of the regular hexagon formed by the overlapping projections of layers A and B" is incorrect because the misalignment of AB stacking causes the overlapping area of the projection to no longer be the center of the original hexagon. Therefore, the interlayer sodium ions should occupy the projection of the intersection of three adjacent polygons, similar to the intercalation sites of lithium ions in graphite. Sodium ions are located at the trifurcated voids where the vertices of adjacent A and B layer polygons intersect, with one sodium ion at each trifurcation point.

F.ABAB堆叠意味着相邻两层（A和B）的环不是对齐的，而是错位的共中心大小环交错，因此俯视图中A层和B层的多边形投影应错开。题目描述"钠离子填在夹层里且每层钠离子位置相同"，说明钠离子位于两层之间。若钠离子位于重叠区域中心，AB层错位后重叠区域可能不居中。 “钠离子位于A层与B层投影重叠形成的正六边形中心”是错误的，因为AB堆叠的错位导致投影重叠区域不再是原六边形的中心。故层间钠离子应占据相邻三个多边形的交点投影，类似石墨中锂离子的嵌入位点。钠离子位于相邻A、B层多边形顶点交汇的三叉空隙，每个三叉点一个钠离子。
