| Abstract: | Two novel 1D complexes, Ni(hto){Au(CN)2}2]Ni(hto)](ClO4)2 · 4H2O (hto = 1,3,6,9,11,14-hexaazatricyclo12.2.1.16,9]octadecane, in Scheme 1.) (1) and Co(dien)2]{Au(CN)2}3] · 2H2O (dien = diethylenetriamine) (2) have been synthesized and characterized. The crystal structure of 1 confirmed the presence of nickel (II) chains via Au-Au interactions. The coordination geometry around the six-coordinate nickel (II) ion is slightly distorted octahedral with four nitrogen atoms of the macrocycle and two nitrogen atoms of the cyanides. The presence of Au-Au interactions have effectively increased the zero dimensional coordination polymer to a one dimensional system. In the complex 2, there are one cation, three anions, and two water molecules in the asymmetric unit. These components are interconnected through a combination of aurophilic attractions and hydrogen bonds and formed 1D chains. |
