{?-6,6'-Dieth-oxy-2,2'-[ethane-1,2-diylbis(nitrilo-methyl-idyne)]diphenolato}trinitratoholmium(III)nickel(II).

ABSTRACT: In the title heteronuclear Ni(II)-Ho(III) complex (systematic name: {?-6,6'-dieth-oxy-2,2'-[ethane-1,2-diylbis(nitrilo-methyl-idyne)]diphenolato-1?(4)O(1),O(1'),O(6),O(6'):2?(4)O(1),N,N',O(1')}trinitrato-1?(6)O,O'-holmium(III)nickel(II)), [HoNi(C(20)H(22)N(2)O(4))(NO(3))(3)], with the hexa-dentate Schiff base compartmental ligand N,N'-bis-(3-ethoxy-salicyl-idene)ethyl-enediamine (H(2)L), the Ho and Ni atoms are doubly bridged by two phenolate O atoms of the Schiff base ligand. The coordination of Ni is square-planar with the donor centers of two imine N atoms and two phenolate O atoms. The holmium(III) center has a tenfold -coordination environment of O atoms, involving the phenolate O atoms, two eth-oxy O atoms and two O atoms each from the three nitrates. Weak C-H?O and O?Ni [3.383?(4)?Å] inter-actions generate a two-dimensional zigzag sheet.

The four-coordinate Zn(II) ion has a distorted square-planar coordination and is N(2)O(2)-chelated by the Schiff base ligand.

{6,6'-Dieth-oxy-2,2'-[2,2-dimethyl-propane-1,3-diylbis(nitrilo-methyl-idyne)]diphenolato}nickel(II) monohydrate.

Project description:In the title complex, [Ni(C(23)H(28)N(2)O(4))]·H(2)O, the Ni(II) ion is coordinated by the N(2)O(2) unit of the tetra-dentate Schiff base ligand in a slightly distorted planar geometry. The asymmetric unit of the title compound comprises one complex mol-ecule and a water mol-ecule of crystallization. The H atoms of the water mol-ecule make bifurcated inter-molecular hydrogen bonds with the O atoms of the phenolate and eth-oxy groups with R(1) (2)(5) and R(1) (2)(6) ring motifs, which may, in part, influence the mol-ecular configuration. The dihedral angle between the two benzene rings is 31.43 (5)°. The crystal structure is further stabilized by inter-molecular C-H⋯O and C-H⋯π inter-actions, which link neighbouring mol-ecules into one-dimensional extended chains along the a axis. An inter-esting feature of the crystal structure is the short inter-molecular C⋯C [3.3044 (14) Å] contact which is shorter than the sum of the van der Waals radii.

The coordination environment of the Ni(2+) ion is distorted square-planar and it is N(2)O(2) coordinated by the 6,6'-dimeth-oxy-2,2'-[ethane-1,2-diylbis(nitrilo-methyl-idyne)]diphenolate Schiff base ligand. The Na(+) atom is chelated by the four O atoms of the Schiff base ligand, a water ligand and a dicyanamide anion. The structure displays inter-molecular O-H⋯N hydrogen bonding.

Aqua-{6,6'-dimeth-oxy-2,2'-[ethane-1,2-diylbis(nitrilo-methyl-idyne)]diphenolato}nickel(II).

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.

Dichlorido{μ(3)-6,6'-dieth-oxy-2,2'-[ethane-1,2-diylbis(nitrilo-methyl-idyne)]diphenolato}octa-methyldi-μ(3)-oxido-tetra-tin(IV).

Project description:In the title tetra-nuclear tin(IV) complex, [Sn(4)(CH(3))(8)(C(20)H(22)N(2)O(4))Cl(2)O(2)], there are three completely different tin-atom coordinations. One metal atom (site symmetry 2) adopts a distorted penta-gonal-bipyramidal SnC(2)N(2)O(3) coordination arising from the N,N',O,O'-tetra-dentate deprotonated Schiff base, two methyl groups in the axial sites and a μ(3)-O atom that also bonds to two further Sn atoms. Two symmetry-equivalent Sn atoms adopt very distorted SnC(2)O(4) arrangements that could be described as penta-gonal-bipyramidal with one equatorial vertex missing and the C atoms in the axial site. The final Sn atom (site symmetry 2) adopts an SnC(2)Cl(2)O trigonal-bipyramidal arrangement, with Cl atoms in the axial sites. As well as the two Sn atoms, one O atom lies on a twofold rotation rotation axis, and another is disordered about the axis. The terminal eth-oxy group is disordered over two sets of sites with equal occupancy.
