Bis{?-2,2'-[ethane-1,2-diylbis(nitrilo-methyl-idyne)]diphenolato}dinickel(II).

ABSTRACT: The asymmetric unit of the title compound, [Ni(2)(C(16)H(14)N(2)O(2))(2)], contains an Ni(II) cation which is coordinated by two imine N atoms and by two phenolate O atoms of the salen ligand {salen = N,N'-bis-(salicyl-idene)ethane-1,2-diamine or 2,2'-[ethane-1,2-diyl-bis(nitrilo-methyl-idyne)]diphenol}, leading to a distorted square-planar conformation. When a secondary Ni-O inter-action > 2.41?Å to the neighbouring phenolate O atom is considered, two mol-ecules are linked into a centrosymmetric dimer with an overall square-pyramidal coordination for the Ni(II) cation. Weak ?-? inter-actions with a shortest interplanar distance of 3.704?Å help to stabilize the crystal structure.

Project description:The reported structure is a monoclinic polymorph of the title compound, [Mn(2)(C(16)H(14)N(2)O(2))(2)(NCS)(2)], which has been characterized previously in an ortho-rhom-bic form. Each Mn(III) atom is chelated by a tetra-dentate 2,2'-[ethane-1,2-diylbis(nitrilo-methyl-idyne)]diphenolate ligand and by the N atom of a thio-cyanate anion, in a square-pyramidal arrangement. The complexes form centrosymmetric dimers, with an Mn-O contact of 2.557 (3) Å trans to each thio-cyanate anion, completing a distorted octa-hedral coordination geometry.

Project description:In the title compound, [Fe(2)(C(16)H(12)Br(2)N(2)O(2))(2)O], the complete mol-ecule is generated by twofold symmetry, with the bridging O atom, which links the iron centres, lying on the roatation rotation axis. The Fe(III) ion is chelated by the N,N,O,O-tetra-dentate Schiff base dianion, resulting in an FeN(2)O(3) square-based pyramid, with the two N atoms in the basal plane.

Project description:The title compound, [Cu(C(22)H(22)N(2)O(8))], is a tetra-dentate Schiff base complex. The Cu(II) ion has a nearly square-planar geometry, being coordinated by two N atoms and two O atoms. The two chemically equivalent halves of the mol-ecule are crystallographically independent. One of the carboxylic acid methyl ester units is located in the main plane of the mol-ecule and the other is rotated by 65.3?(5)° with respect to this unit. In the crystal structure, there are ?-? stacking inter-actions between adjacent six-membered chelate rings, with centroid-to-centroid distances of 3.602?(2)?Å.

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.

Aqua-{2,2-[ethane-1,2-diylbis(nitrilo-methyl-idyne)]diphenolato}(3-nitro-benzoato)manganese(III).

Project description:The title compound, [Mn(C(16)H(14)N(2)O(2))(C(7)H(4)NO(4))(H(2)O)], is a Jahn-Teller-distorted manganese(III) monomer with an octa-hedral geometry. The tetra-dentate Schiff base accommodates the Mn(III) ion at the centre of a nearly planar square. The axial positions are occupied by a monodentate carboxyl-ate group and a water mol-ecule. Adjacent monomers inter-act through hydrogen bonding between the noncoordinated C=O group of the carboxyl-ate and the coordinated water mol-ecule to produce chains extending parallel to the b axis.

All the atoms of the meth-oxy substitutents are in the plane of the ring to which they are attached except for one which deviates slightly [0.365?(3)?Å]. In the crystal, weak C-H?O inter-molecular inter-actions connect the mol-ecules.
