A tetranuclear cadmium(II) complex based on the 2-(quinolin-8-yloxy)acetonitrile ligand

Abstract

The hydrothermal reaction of 2-(quinolin-8-yloxy)acetonitrile and Cd(ClO4)2yielded the noncentrosymmetric coordination complex tetrakis[μ-2-(quinolin-8-yloxy)acetato]tetrakis[μ-2-(quinolin-8-yloxy)acetonitrile]tetracadmium tetrakis(perchlorate) dihydrate, [Cd4(C11H8NO3)4(C11H8N2O)4](ClO4)4·2H2O. The local coordination environment around the CdIIcation can be best described as a capped octahedron defined by two N atoms and five O atoms from three ligands. The CdIIcations are linked by the ligands with Cd—O—Cd and Cd—O—C—C—O—Cd bridges, forming tetranuclear units, there being two independent tertranuclear units in the structure. The fourfold rotoinversion centre sits at the centre of each Cd4core. The two perchlorate anions in the asymmetric unit are linked by the water molecule through O—H...O hydrogen bonds.
