Syntheses,crystal structures and magnetic properties of two new 3-cyanobenzate coordination complexes

摘要

Two new 3-cyanobenzate complexes,[Cu(3-cba)_2(Py)(H_2O)]_n 1 and [Cd(3-cba)_2(Py)2(H_2O)] _2(3-cba=3-cyanobenzate,Py=pyr-idine),were synthesized and structurally characterized by single-crystal X-ray diffraction.Three different coordination modes of 3-cba group exist in the two obtained complexes,which results in different molecular architectures:1 with a 1-D chained structure and 2 with an isolated configuration.Variable-temperature magnetic susceptibility data show the presence of antiferromagnetic interactions in 1.
