چکیده
The title ZnII complex, [Zn(NCS)2(C20H21N3)], has been characterized by synchrotron single-crystal diffraction and FT-IR spectroscopy. The central ZnII ion 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-N S-ppme and Zn-NNCS bond 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 the ac plane.

The asymmetric unit of the title compound, [Zn(NCS)(2)(C(13)H(19)N(3)O)], contains two crystallographically independent mol-ecules. In each mol-ecule, the Zn(II) ion is five-coordinated by the N,N',N"-tridentate Schiff base and the N atoms of two thio-cyanate ligands in a distorted square-pyramidal geometry. The two mol-ecules differ mainly in the deviations from the ideal geometry, with τ valu...

In the title compound, [Mn(NCS)(2)(C(13)H(19)N(3)O)(H(2)O)], the Schiff base acts as an N,N',N"-tridentate ligand, forming two five-membered chelating rings with the Mn(II) atom. The distorted octa-hedral geometry around the metal atom is completed by two cis-positioned N-bound thio-cyanate ligands and one water mol-ecule. In the crystal, adjacent mol-ecules are linked through O-H⋯O, O-H⋯S and ...

In the title compound, [Co(NCS)(2)(C(19)H(17)N(5)O(2))(2)(CH(3)OH)(2)], the Co(II) atom lies on an inversion center and is coordinated by two isothio-cyanate N atoms, two O atoms of methanol mol-ecules and two pyridine N atoms in a slightly distorted octa-hedral environment. Inter-molecular O-H⋯O and N-H⋯N hydrogen bonds join the complex mol-ecules into layers parallel to the bc plane.

The complete mol-ecule of the title mononuclear zinc(II) complex, [Zn(NCS)(2)(C(13)H(13)N(3))], is generated by crystallographic twofold symmetry, with the metal atom lying on the rotation axis. The pendant methyl group of the ligand is statistically disordered over two sites. The Zn(2+) cation is coordinated by the N,N',N''-tridentate Schiff base ligand, and by two thio-cyanate N atoms, formin...
