合成了一种新型有机多羧酸HOOCCH2OC6H4N(CH2COOH)2(H3L),并用它与六水合硫酸镍在常温下反应得到配合物[Ni3(L)2(H2O)12].6H2O(1)的单晶。经单晶结构测定,该配合物中含有两种不同配位环境的镍(Ⅱ)离子,一种镍(Ⅱ)离子与配体中氮原子上的两个亚甲基羧基配位,另一种与六个水分子配位.配体中与氧原子连接的亚甲基羧基没有配位。配合物(1)属三斜晶系,P-1空间群,晶胞参数为:a=0.730 1(14)nm,b=1.059 7(17)nm,c=1.363 9(16)nm,α=97.14(8)°,β=91.26(6)°,γ=96.50(8)°,V=1.040(3)nm3,Z=1.
A new type of organic polycarboxylic acid HOOCCH2OC6H4N (CH2COOH) 2 (H3L) was synthesized and reacted with nickel sulfate hexahydrate at room temperature to obtain the complex of [Ni3 (L) 2 (H2O) 12] crystal. The single crystal structure of the complex contains two kinds of nickel (Ⅱ) ions with different coordination environments. One kind of nickel (Ⅱ) ion is coordinated with two methylene carboxyl groups on the nitrogen atom in the ligand. The other The species coordinates with six water molecules, and the methylene carboxyl group attached to the oxygen atom in the ligand does not coordinate. The complex (1) belongs to the triclinic and P-1 space group with unit cell parameters of a = 0.730 1 (14) nm, b = 1.059 7 (17) nm and c = 1.363 9 = 97.14 (8) °, β = 91.26 (6) °, γ = 96.50 (8) °, V = 1.040 (3) nm3, Z = 1.
