{6,6'-Dimeth-oxy-2,2'-[(cyclo-hexane-1,2-di-yl)bis-(nitriliomethyl-idyne)]diphenolato}trinitratolanthanum(III) methanol monosolvate.

ABSTRACT: In the title mononuclear complex, [La(NO(3))(3)(C(22)H(26)N(2)O(4))]·CH(3)OH, the La(III) ion is coordinated by three bidentate nitrate counter-ions and one zwitterionic 6,6'-dimeth-oxy-2,2'-[(cyclo-hexane-1,2- di-yl)bis-(nitriliomethyl-idyne)]diphenolate ligand through two phenolate and two meth-oxy O atoms, while the protonated N atoms remain uncoordinated. H atoms located on the two N atoms are involved in intra-molecular hydrogen bonds with the deprotonated phenol O atoms, indicating that proton migration occurs during the lanthanum complexation.

Project description:The title Mn(III) compound, {[Mn(C(18)H(18)N(2)O(4))(CH(3)COO)]·CH(3)OH}(n), was synthesized by a reaction between mangan-ese(II) acetate and ethyl-enebis(4-meth-oxy-salicylaldimine). The structure is made up of bis-(4-meth-oxy-salicyldene)ethyl-enediaminatomanganese(III) units bridged by acetate groups, with Mn-N = 1.9786?(9), Mn-O = 1.8784?(10) and Mn-O(acetate) = 2.056?(9) and 2.2571?(9)?Å, forming a one dimensional polymer (-Mn-acetate-Mn-acetate-) along [100]. The Mn(III) atom is in a Jahn-Teller-distorted octa-hedral environment with cis angles ranging from 81.87?(4) to 96.53?(4)° and trans angles ranging from 166.11?(3) to 173.93?(3)°. The methanol solvent mol-ecule is hydrogen bonded to the phenolate O atom. In addition to this classical hydrogen bond, there are weak C-H?O inter-actions. The structure was determined from a crystal twinned by pseudo-merohedry.

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.

Project description:The title complex, [Cu(C(18)H(16)Br(2)N(2)O(4))(H(2)O)], lies on a crystallographic mirror plane with the Cu(II) ion coordinated by two N atoms and two O atoms of a tetra-dentate Schiff base ligand and one O atom from a water ligand in a slightly distorted square-pyramidal environment. The mirror plane, which coincides with the Cu-O(water) bond, imposes disorder of the atoms of the ethyl-ene group. In the crystal structure, inter-molecular O-H?O hydrogen bonds link complex mol-ecules into extended chains along [100].
