{2,2'-[Ethane-1,2-diylbis(nitrilo-methan-yl-yl-idene)]diphenolato}(iso-propano-lato)aluminium di-chloro-methane hemisolvate.

ABSTRACT: In the title compound, [Al(C16H14N2O2)(C3H7O)]·0.5CH2Cl2, the salen complex is monomeric and the dichlormethane solvent mol-ecule lies on a crystallographic twofold axis. The central Al atom is fivefold coordinated and possesses a square-based pyramidal environment. The Al-OAlk( (i) prop-yl) bond [1.7404 (14) Å] is much shorter than the Al-OAr(salen) bond lengths [1.7974 (15) and 1.8094 (14) Å]. The iso-propyl-oxo group forms an intra-molecular C-H⋯N hydrogen bond. In the crystal, the complex mol-ecules are linked by weak C-H⋯O inter-actions.

{2,2'-[(2,2-Dimethyl-propane-1,3-di-yl)bis-(nitrilo-methyl-idyne)]diphenolato}palladium(II) ethanol hemisolvate.

Project description:The asymmetric unit of the title complex, [Pd(C(19)H(20)N(2)O(2))]·0.5C(2)H(5)OH, contains two mol-ecules of a Pd(II) complex of a Schiff base ligand with an N(2)O(2) donor set and one ethanol mol-ecule. The Pd(II) centers are in distorted square-planar geometries with the N(2)O(2) donor atoms of the tetra-dentate Schiff base dianions. The ethanol mol-ecule takes part in an O-H⋯O hydrogen bond. In the crystal structure, mol-ecules are stacked approximately along the b-axis direction. The O atom and three H atoms of the solvent molecule are disordered over two positions; the site occupancy factors are ca 0.8 and 0.2.

Project description:The title compound, [Cu(C(20)H(20)N(2)O(2))], crystallizes with two independent mol-ecules in the asymmetric unit. In each mol-ecule, the Cu(II) atom occupies the tetra-dentate N(2)O(2) cavity of the salen-type Schiff base ligand, adopting a distorted square-planar geometry with r.m.s. deviations of the coordin-ating atoms of 0.0522 (2) and 0.1128 (4) Å. No hydrogen bonds or π-π stacking inter-action are observed.

Bis{μ-2,2'-[ethane-1,2-diylbis(nitrilo-methyl-idyne)]diphenolato}dinickel(II).

Project description:The asymmetric unit of the title compound, [Ni(2)(C(16)H(14)N(2)O(2))(2)], contains an Ni(II) cation which is coordinated by two imine N atoms and by two phenolate O atoms of the salen ligand {salen = N,N'-bis-(salicyl-idene)ethane-1,2-diamine or 2,2'-[ethane-1,2-diyl-bis(nitrilo-methyl-idyne)]diphenol}, leading to a distorted square-planar conformation. When a secondary Ni-O inter-action > 2.41 Å to the neighbouring phenolate O atom is considered, two mol-ecules are linked into a centrosymmetric dimer with an overall square-pyramidal coordination for the Ni(II) cation. Weak π-π inter-actions with a shortest interplanar distance of 3.704 Å help to stabilize the crystal structure.

Project description:The title complex, [Ni(C(18)H(18)N(2)O(4))(H(2)O)], lies on a mirror plane with the Ni(II) ion coordinated by two N and two O atoms of a tetra-dentate Schiff base ligand and one water O atom in a distorted square-pyramidal enviroment. The -CH(2)-CH(2)- group of the ligand is disordered equally over two sites about the mirror plane. The dihedral angle between the mean planes of the two symmetry-related chelate rings is 37.16?(6)°. In the crystal structure, inter-molecular O-H?O hydrogen bonds link complex mol-ecules into one-dimensional chains along [100] and these chains are linked, in turn, by very weak inter-molecular C-H?O hydrogen bonds into a two-dimensional network.
