Bis{?-4,4',6,6'-tetra-tert-butyl-2,2'-[N-(2-oxidoeth-yl)imino-dimethyl-ene]diphenolato}dialuminium(III).

ABSTRACT: The title compound, [Al(2)(C(32)H(48)NO(3))(2)], exists as a dimer with bridging ethoxide groups. It was isolated from a reaction mixture of the parent ligand and trimethyl-aluminium in tetra-hydro-furan. The geometry around the Al(III) atom is a slightly distorted trigonal-bipyramid, typical of atrane derivatives.

Aqua-{4,4',6,6'-tetra-fluoro-2,2'-[(piperazine-1,4-di-yl)dimethyl-ene]diphenolato}copper(II).

Project description:In the title compound, [Cu(C(18)H(16)F(4)N(2)O(2))(H(2)O)], the Cu(II) atom shows a distorted square-pyramidal coordination geometry with the N,N',O,O'-tetra-dentate piperazine-diphenolate ligand forming the basal plane. The apical site is occupied by the O atom of a coordinated water mol-ecule. Neighbouring complexes are associated through inter-molecular O-H?O and O-H?F hydrogen bonds between the water mol-ecule and a phenolate O atom or an F atom from an adjacent ligand, respectively, forming a centrosymmetric dimer. Dimers are linked by additional inter-molecular C-H?O and C-H?F hydrogen bonds, giving infinite chains propagating along the a axis.

Project description:The title compound, C(34)H(54)N(2)O(2)·0.25H(2)O, the organic mol-ecule, a potential tetra-dentate ligand with a bulky phenolic donor, has overall mirror symmetry. A partially occupied water mol-ecule of solvation is present in the lattice. The six-membered 1,3-diazinane ring displays a chair conformation. An intra-molecular O-H⋯N hydrogen bond ocurs. In the crystal, mol-ecules are linked by O-H⋯O inter-actions.

(4,4',6,6'-Tetra-tert-butyl-2,2'-{[2-(di-methyl-amino)-ethyl]-nitrilo-bis-(methyl-ene)}diphenolato)dioxidomolyb-denum(VI) chloro-form monosolvate.

Project description:In the title compound, [Mo(C(34)H(54)N(2)O(2))O(2)]·CHCl(3), the molybdenum(VI) ion exhibits a cis-dioxide distorted octa-hedral geometry. Two anionic phenolate O-atom donors and two neutral N-atom donors of the ligand are trans and cis, respectively. The Mo=O bond lengths and the O=Mo=O bond angle are typical for six-coordinated dioxomolyb-denum(VI) complexes. The Mo-N bond lengths are longer than 2.30 Å, as expected for a trans O=Mo-N structure.

Project description:The Zn atom in the title acetonitrile solvate, [Zn(C(34)H(42)N(4)O(2))(C(2)H(6)OS)]·CH(3)CN, exists in a distorted square-pyramidal geometry with the basal plane defined by the N(2)O(2) atoms of the tetra-dentate Schiff base and with the dimethyl sulfoxide O atom in the apical position. The tetra-dentate mode of coordination of the Schiff base ligand leads to a five-membered ZnN(2)C(2) chelate ring which adopts an envelope conformation with the Zn atom at the flap, and two six-membered ZnOC(4)N chelate rings, one of which is approximately planar (r.m.s. deviation = 0.054 Å) but the other has significant puckering (r.m.s. deviation = 0.203 Å).
