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

Two new 3-cyanobenzate complexes, [Cu(3-cba)2(Py)(H2O)]n 1 and [Cd(3-cba)2(Py)2(H2O)] 2 (3-cba = 3-cyanobenzate, Py = pyridine), 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.
