{μ-6,6'-Dimeth-oxy-2,2'-[ethane-1,2-diyl-bis(nitrilo-methyl-idyne)]diphenolato-1κO,O,O,O:2κO,N,N',O}(methanol-1κO)(perchlorato-1κO)nickel(II)sodium.

ABSTRACT: The mol-ecule of the title compound, [NaNi(C(18)H(18)N(2)O(4))(ClO(4))(CH(3)OH)], is almost planar, the maximum deviation from the molecular plane being 5.3 (1) Å. The Ni(2+) ion is N(2)O(2) coordinated by the Schiff base ligand, leading to a slightly distorted square-planar environment. The Na atom is chelated by the four O atoms of the Schiff base ligand and is coordinated by the O atoms of a methanol ligand and a perchlorate anion. The perchlorate ion is disordered over two sites with occupancies 0.723 (12):0.277 (12).

Project description:In the title heteronuclear Zn(II)-Sm(III) complex, [SmZn(C(18)H(18)N(2)O(4))(NO(3))(3)(CH(3)CH(2)OH)], with the hexa-dentate Schiff base compartmental ligand N,N'-bis-(3-methoxy-salicyl-idene)ethyl-enediamine (H(2)L), the Sm(III) and Zn(II) ions are triply bridged by two phenolate O atoms from the Schiff base ligand and one nitrate anion. The five-coordinate Zn(II) ion is in a square-pyramidal geometry formed by the donor centers of two imine N atoms, two phenolate O atoms and one of the bridging nitrate O atoms. The Sm(III) center is in a ten-fold coordination of O atoms, involving the phenolate O atoms, two meth-oxy O atoms, one ethanol O atom, and two O atoms from two nitrate anions and one from the bridging nitrate anion. In the crystal, inter-molecular O-H⋯O and C-H⋯O inter-actions generate a layer structure extending parallel to (101).

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.

Aqua-{4,4'-dibromo-6,6'-dimeth-oxy-2,2'-[ethane-1,2-diylbis(nitrilo-methyl-idyne)]diphenolato}copper(II).

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.
