Bis{2-[2-(isopropyl-ammonio)ethyl-imino-meth-yl]-6-methoxy-phenolato}nickel(II) dithio-cyanate.

ABSTRACT: The title complex, [Ni(C(13)H(20)N(2)O(2))(2)](NCS)(2), consists of a centrosymmetric mononuclear four-coordinate nickel(II) complex cation and two thio-cyanate anions. The Ni atom is located on an inversion center and is coordinated by two phenol O atoms and two imine N atoms from two equivalent Schiff base ligands, in a square-planar geometry. In the crystal structure, the amino H atoms are involved in N-H⋯O hydrogen bonds with the phenol and meth-oxy O atoms of the ligand, and in N-H⋯N hydrogen bonds with the N atoms of the thio-cyanate anions, which sit above and below the Ni atom.

Bis{2-eth-oxy-6-[2-(isopropyl-ammonio)ethyl-imino-meth-yl]phenolato}dithio-cyanato-nickel(II).

Project description:In the mononuclear title complex, [Ni(NCS)(2)(C(14)H(22)N(2)O(2))(2)], the Ni atom lies on an inversion centre. It is chelated by the phenolate O and imine N atoms from two zwitterionic Schiff base ligands, and is also coordinated by the N atoms from two thio-cyanate ligands, giving a slightly distorted octa-hedral geometry. Intra-molecular N-H⋯O and N-H⋯N hydrogen bonds are observed.

Project description:In the title compound, [Cu(C(13)H(20)N(2)O(2))(2)](ClO(4))(2), the Cu(II) atom in the complex dication is chelated by two phenolate O atoms and two imine N atoms from two zwitterionic 2-[2-(isopropyl-ammonio)ethyl-imino-meth-yl]-5-methoxy-phenolate ligands, forming a distorted square-planar geometry. One of the perchlorate anions is disordered over two sites with occupancies of 0.611?(15) and 0.389?(15). Intra-molecular N-H?O hydrogen bonds are observed in the complex dication. In the crystal structure, the perchlorate anions are linked to complex dications by inter-molecular N-H?O hydrogen bonds.

Dichlorido{2-[2-(dimethyl-ammonio)ethyl-imino-meth-yl]-6-methoxy-phenolato}zinc(II).

Project description:The structure of the title complex, [ZnCl(2)(C(12)H(18)N(2)O(2))], contains a zwitterionic Schiff base ligand. The complex adopts a distorted tetra-hedral coordination geometry around the metal centre with the Schiff base ligand coordinated in a bidentate fashion via the imine N and phenolate O atoms. In the crystal, inter-molecular N-H?O and C-H?Cl hydrogen bonds link the mol-ecules into chains parallel to the c-glide planes.

Bis(2-meth-oxy-6-{[2-(methyl-ammonio)eth-yl]imino-meth-yl}phenolato)thio-cyanato-zinc(II) thio-cyanate hemihydrate.

Project description:The title mononuclear zinc(II) complex, [Zn(C(11)H(16)N(2)O(2))(2)(NCS)]NCS·0.5H(2)O, consists of a complex cation, a thio-cyanate anion, and half of a water mol-ecule. The Zn(II) atom in the cation is five-coordinated by two imine N and two phenolate O atoms from two bidentate Schiff base ligands, and by one N atom of a thio-cyanate ligand, forming a distorted trigonal-bipyramidal geometry. The ammonio H atoms are involved in hydrogen bonding with the ligand O atoms and the solvent water molecules (site occupation factor 0.5), which partially determines the conformation of the ligands.

Project description:The title complex, [Zn(NCS)(C(13)H(20)N(2)O(2))(2)]NO(3), consists of a complex mononuclear Zn(II) cation and a nitrate counter-anion.

The nitrate counter-ions are linked to the cations through N-H?O hydrogen bonds.
