Aqua-chlorido{6,6'-dimeth-oxy-2,2'-[ethane-1,2-diylbis(nitrilo-dimethyl-idyne)]diphenolato-κO,N,N',O}cobalt(III) monohydrate.

ABSTRACT: The title compound, [Co(C(18)H(18)N(2)O(4))Cl(H(2)O)]·H(2)O, contains a distorted octa-hedral cobalt(III) complex with a 6,6'-dimeth-oxy-2,2'-[ethane-1,2-diylbis(nitrilo-dimethyl-idyne)]diphenolate ligand, a chloride and an aqua ligand, and also a disordered water solvent mol-ecule (half-occupancy). The Co(III) ion is coordinated in an N(2)O(3)Cl manner. Weak O-H⋯O hydrogen bonds may help to stabilize the crystal packing.

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].

Aqua-{6,6'-dimeth-oxy-2,2'-[ethane-1,2-diylbis(nitrilo-methyl-idyne)]diphenolato}methano-lmanganese(III)) perchlorate hemihydrate.

Project description:The asymmetric unit of the title compound, [Mn(C(18)H(18)N(2)O(4))(CH(3)OH)(H(2)O)]ClO(4)·0.5H(2)O, contains two complex cations and two perchlorate anions, one of which is disordered over two positions in a 0.767?(8):0.233?(8) ratio. The Mn(III) atoms are in distorted octa-hedral environments. In addition to the equatorial tetra-dentate salicylaldimine ligand, each Mn is axially coordinated by both a methanol and a water mol-ecule. The complex is a dimer held together by multiple strong and weak hydrogen-bonding inter-actions between the coordinated water mol-ecule on one monomer with all the phenolic and meth-oxy O atoms on the other monomer. In addition, the two perchlorate anions are linked by hydrogen bonds to the two methanol mol-ecules coordinated to each Mn center. The Mn-O phenolic bond distances range from 1.868?(2) to 1.882?(2)?Å while the Mn-N distances range from 1.978?(2) to 1.981?(2)?Å. Mn-O distances for the axial water and methanol ligands are longer at 2.226?(2)/2.257?(2) and 2.313?(2)/2.324?(2)?Å, reflecting the usual Jahn-Teller distortion as found in Mn(III) complexes.

Project description:The mol-ecule of the title compound, [NaNi(C(18)H(18)N(2)O(4))(C(2)N(3))(H(2)O)], is approximately planar, with a maximum deviation from the mol-ecular plane of 0.770 (5) Å. 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.

Project description:The title compound, [Mn(C(18)H(18)N(2)O(4))(C(7)H(5)O(3))(H(2)O)], was synthesized by a template reaction of ethane-1,2-diamine and 3-methoxy-salicylaldehyde in presence of manganese(II) 4-hydroxy-benzoate. The Jahn-Teller-distorted manganese(III) centre has an octa-hedral geometry. Extensive O-H⋯O hydrogen-bonding inter-actions generate a two-dimensional sheet structure parallel to (103).

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.

Project description:The Mn(III) atom in the title complex, [Mn(C(18)H(18)N(2)O(4))(CHO(2))(H(2)O)]·2H(2)O, is O,N,N',O'-chelated by the deproton-ated Schiff base; the four chelating atoms form an approximate square, with the O atoms of the water mol-ecule and the formate ion in axial positions above and below the square plane. Two metal-bearing mol-ecules are linked by an O-H(water)?O hydrogen bond about a center of inversion, generating a hydrogen-bonded dinuclear species; adjacent dinuclear units are linked through the lattice water mol-ecules, forming a three-dimensional network.
