Bimetallic Ag(I)-Cu(II) Assembly with Extended Oxamido-Bridged: Synthesis, Crystal Structure and Magnetism

摘要

A new bimetallic compound Cu2(oxae)(H2O)2Ag2(CN)4 (1) (oxae = N,N'-bis(2-amino-ethyl)oxamido dianion) was isolated and structurally characterized. Compound 1 crystallizes in the monoclinic system, with space group P2_1/c and unit cell constants a = 14.033(18), b = 7.165(9), c = 9.378(12) 8, β = 103.890(14)° and Z= 2. The complex 1 consists of the oxamido-bridged binuclear copper(II) unit and two linear cyanoargentate anions acting as monochelate ligands. The coordinated environment of the Cu atom is a square prism. The complex 1 is self-assembled into three-dimensional (3D) network via hydrogen bonds. The magnetic properties of 1 have been studied as well.
