Dibromido{(E)-2-eth-oxy-6-[3-(methyl-ammonio)propyl-iminometh-yl]phenol-ato}zinc(II).

ABSTRACT: The title complex, [ZnBr(2)(C(13)H(20)N(2)O(2))], is a mononuclear zinc(II) compound derived from the zwitterionic form of the Schiff base (E)-2-eth-oxy-6-((3-(methyl-amino)propyl-imino)meth-yl)phenol. The Zn(II) atom is four-coordinated by the imine N and phenolate O atoms of the Schiff base ligand, and by two bromide ions, in a tetra-hedral coordination geometry. Adjacent mol-ecules are linked through inter-molecular N-H⋯O hydrogen bonds, forming chains running along the b axis.

Redetermination of {2-[3-(dimethyl-ammonio)propyl-imino-meth-yl]phenol-ato}-dithio-cyanato-zinc(II).

Project description:In comparison with the previous refinement of the title complex, [Zn(NCS)(2)(C(12)H(18)N(2)O)], the present redetermination reveals a different location of the non-carbon attached H atom. Whereas in the previous refinement this H atom was modelled as part of a phenol OH group, the present study indicates a zwitterionic Schiff base ligand with a deprotonated OH group and a protonated tertiary amine group. The Zn(II) atom is four-coordinated by one O and one imine N atoms of the 2-[3-(dimethyl-ammonio)propyl-imino-meth-yl]phenolate Schiff base ligand, and by two N atoms from two thio-cyanate ligands, forming a distorted tetra-hedral geometry. In the crystal structure, adjacent mol-ecules are linked through inter-molecular N-H⋯O hydrogen bonds, forming a chain in the [101] direction.

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.
