{μ-6,6'-Dimeth-oxy-2,2'-[propane-1,3-diylbis(nitrilo-methyl-idyne)]-diphenolato}-trinitratocopper(II)lutetium(III) acetone solvate.

ABSTRACT: In the title complex, [CuLu(C(19)H(20)N(2)O(4))(NO(3))(3)]·CH(3)COCH(3), the Cu(II) ion is four-coordinated in a square-planar geometry by two O atoms and two N atoms from the deprotonated Schiff base. The Lu(III) ion is ten-coordinate, chelated by three nitrate groups and linked to the four O atoms of the deprotonated Schiff base. A mol-ecule of acetone is present as a solvate.

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.

Project description:In the asymmetric unit of the title compound, [Cu(C(19)H(20)N(2)O(4))(H(2)O)], there are two independent mononuclear Cu(II) complexes. The coordination environment of each Cu(II) ion is square-pyramidal completed by two N atoms and two O atoms forming the basal plane, and one O atom of the water mol-ecule occupying the apical position. Neighbouring complexes are connected via O-H?O hydrogen bonds between the water mol-ecule and the meth-oxy group, forming a chain structure along the a axis. The propyl-ene groups of the two independent complexes are disordered over two positions with site occupancies of 0.361?(7):0.639?(7) and 0.224?(8):0.776?(8). The crystal under investigation was a partial inversion twin.
