Abstract Cu(I) and Ag(I) iodidometalates have been investigated for both their rich structural chemistry, as well as for useful properties like luminescence. Here, we present the synthesis and crystal structure of (BzA)[MI2] · 0.5 H2O (BzA = benzylammonium; M=Cu (1), Ag (2)). The two compounds are isostructural and show a previously unknown layered anion motif that can be described as a 44 net constructed via corner-sharing of M2I6 subunits, built from two edge-sharing MI4 tetrahedra.

两层状 Cu(I) 和 Ag(I) 碘金属酸盐的合成和晶体结构

摘要 Cu(I) 和 Ag(I) 碘金属酸盐因其丰富的结构化学以及有用的性质（如发光）而被研究。在这里，我们介绍了 (BzA)[MI2] · 0.5 H2O（BzA = 苄基铵；M = Cu (1), Ag (2)）的合成和晶体结构。这两种化合物是同构的，并显示出以前未知的分层阴离子基序，可以将其描述为通过 M2I6 亚基的角共享构建的 44 网，由两个共享边缘的 MI4 四面体构建。
