Crystal and Molecular Structure of Bis(benzylamine)bis(thiocyanato)cadmium(II), [Cd(SCN)2(C6H5CH2NH2)2

Abstract

Abstract The crystal and molecular structure of the title complex was determined by means of a single-crystal X-ray diffraction method. A crystal of CdC16H18N4S2, F. W. 442.8, is monoclinic, with the space group of P21⁄n, a=27.390(19), b=5.7709(8), c=5.8733(9) Å, β=90.35(3)°, U=928.3(7) Å3, Z=2, Dm=1.57(3), Dx=1.58 Mg m−3, and μ(Mo Kα)=1.59 mm−1. The cadmium(II) atom is hexa-coordinated being ligated with two thiocyanato (SCN) sulfur atoms, as well as with two SCN and two benzylamine nitrogen atoms, where the respective pairs of the same kinds of atoms are all in transconfiguration. Each cadmium atom is at the center of symmetry, and the coordination structure around the atom is symmetric. The metal atoms are lined along c-axis, and the pair of the neighboring metal atoms are doubly bridged by SCN ions, although the bridges are a little weaker than the other same type adducts.
