title: Crystal structure of {(S)-1-phenyl-N,N-bis-[(pyridin-2-yl)meth-yl]ethanamine-κ3N,N',N''}bis-(thio-cyanato-κN)zinc from synchrotron data.
abstract: The title ZnIIcomplex, [Zn(NCS)2(C20H21N3)], has been characterized by synchrotron single-crystal diffraction and FT-IR spectroscopy. The central ZnIIion has a distorted square-pyramidal coordination geometry, with three N atoms of the chiral (S) 1-phenyl-N,N-bis-[(pyridin-2-yl)meth-yl]ethanamine (S-ppme) ligand and one N atom of a thio-cyanate anion in the equatorial plane, and one N atom of another thio-cyanate anion at the apical position. The average Zn-NS-ppmeand Zn-NNCSbond lengths are 2.183 (2) and 1.986 (2) Å, respectively. In the crystal, inter-molecular C-H⋯S hydrogen bonds and a face-to-face π-π inter-action [centroid-centroid distance = 3.482 (1) Å] link the mol-ecules and give rise to a supra-molecular sheet structure parallel to theacplane.
