摘要
(Cudpt) (ClO4) 2 和K4[Fe(CN) 6]反应得到配位聚合物 (Cudpt) 3 [Fe(CN) 6](ClO4) 2 ·3H2 O(1 ) ,在相似条件下用Cu(ClO4) 2 ,dpt和K4[Fe(CN) 6]反应得到配位聚合物 (Cudpt3 [Fe(CN) 6](ClO4) 2 ·4H2 O(2 ) ,解析了它们的晶体结构。这两个化合物有相同的I.R .和UV—Vis谱 ,但它们的结构却有显著的不同 ,前者是一维链状结构 ,后者则是二维网状结构。
The use of three-coordinate copper(Ⅱ) instead of a four or five-coordinate metal ion signincantly increases the complexity in stereochemistry of the resulting bimetallic assemblies because the geometry about the copper in the assemblies is variably five or six-coordinate together with two or three cyano nitrogen,respectively.A bimetallic assembly(Cudpt) 3[Fe(CN) 6](ClO 4) 2·3H 2O(1) was first obtained by the direct reaction of (Cudpt)(ClO 4) 2 and K 4[Fe(CN) 6].The crystal structure was determinated.In repeated experiments a analogue bitermetallic assembly (Cudpt) 3[Fe(CN) 6](ClO 4) 2·4H 2O(2) which have the same I.R spectra and solid UV-Vis reflectalice of complex 1 was obtained.Surprisingly,two crystal structures were signincantly difierence,the structure of complex 1 is 1-D linear chain but that of the complex 2 is 2-D network.
