Tetra-ethyl-ammonium tris-(thio-cyanato-?N)[tris-(1H-pyrazol-1-yl-?N(2))methane]-nickelate(II).

ABSTRACT: The title salt, (C?H??N)[Ni(NCS)?(C??H??N?)], consists of a tetra-ethyl-ammonium cation and an anion comprising an octa-hedral Ni(II) atom surrounded by three N atoms from a tripodal tris-(pyrazol-1-yl)methane ligand, and three thio-cyanate ligands, each bound at the N-atom end. The ligand Ni-N distances range from 2.097?(2) to 2.127?(2)?Å for the tripodal ligand and from 2.045?(2) to 2.075?(2)?Å for the thio-cyanate ligands. The dihedral angles between the three pyrazole rings are 59.03?(12), 53.09?(10) and 67.90?(10)°.

Crystal structures of tetra-kis-(pyridine-4-thio-amide-κN)bis-(thio-cyanato-κN)cobalt(II) monohydrate and bis-(pyridine-4-thio-amide-κN)bis-(thio-cyanato-κN)zinc(II).

Project description:Reaction of Co(NCS)2 and Zn(NCS)2 with 4-pyridine-thio-amide led to the formation of compounds with composition [Co(NCS)2(C6H6N2S)4]·H2O (1) and [Zn(NCS)2(C6H6N2S)2] (2), respectively. The asymmetric unit of compound 1, consists of one cobalt(II) cation, two thio-cyanate anions, four 4-pyridine-thio-amide ligands and one water mol-ecule whereas that of compound 2 comprises one zinc(II) cation that is located on a twofold rotation axis as well as one thio-cyanate anion and one 4-pyridine-thio-amide ligand in general positions. In the structure of compound 1, the cobalt(II) cations are octa-hedrally coordinated by two terminal N-bonding thio-cyanate anions and by the N atoms of four 4-pyridine-thio-amide ligands, resulting in discrete and slightly distorted octa-hedral complexes. These complexes are linked into a three-dimensional network via inter-molecular N-H⋯S hydrogen bonding between the amino H atoms and the thio-cyanate S atoms. From this arrangement, channels are formed in which the water mol-ecules are embedded and linked to the host structure by inter-molecular O-H⋯S and N-H⋯O hydrogen bonding. In the structure of compound 2, the zinc(II) cations are tetra-hedrally coordinated by two N-bonding thio-cyanate anions and the N atoms of two 4-pyridine-thio-amide ligands into discrete complexes. These complexes are likewise connected into a three-dimensional network by inter-molecular N-H⋯S hydrogen bonding between the amino H atoms and the thio-amide S atoms.
