报道了一个氰根桥连的 4 f 3d一维链状配合物 [Nd(DMF) 4 (H2 O) 2 Cr(CN) 6 ]·H2 O。它是由NdBr3·6H2 O ,H2 salen和 (Bu4 N) 3[Cr(CN) 6 ](摩尔比为 1∶1∶1)在甲醇 DMF混合溶剂中自组装得到。由X 射线单晶衍射结构分析得知其属于单斜晶系 ,空间群为P2 1/c ,晶体数据a =13 2 0 0 (3) ,b =12 .996 (3) ,c=19.2 11(4) ,β =10 9.93(3)°,V =30 98.4 (11) 3,Z =4 ,S =1.0 12 ,R1=0 .0 386 ,wR =0 .0 751。在配合物中 ,每个Nd离子以顺式方式连接 2个Cr离子 ,而每个Cr离子同样以顺式方式连接 2个Nd离子 ,得到一个新颖的类长城链状结构。配位和晶格水分子通过氢键将相邻的NdCr一维链连成三维网状结构
A cyanide bridged 4f 3d one-dimensional chain complex [Nd (DMF) 4 (H 2 O) 2 Cr (CN) 6] · H 2 O was reported. It is self-assembled by NdBr3 · 6H2O, H2 salen and (Bu4N) 3 [Cr (CN) 6] (molar ratio of 1: 1: 1) in methanol DMF mixed solvent. The X-ray single crystal diffraction structure analysis shows that it belongs to the monoclinic system with space group P2 1 / c, crystal data a = 13 2 0 0 (3), b = 12.996 (3), c = 19.2 11 (4), β = 10 9.93 (3) °, V = 30 98.4 (11) 3, Z = 4, S = 1.012, R1 = 0.0386, wR = 0.0751. In the complex, each Nd ion connects two Cr ions in a cis manner, and each Cr ion also connects two Nd ions in a cis manner to obtain a novel class of Great Wall chain structure.
