Dioxido{4,4',6,6'-tetrabromo-2,2'-[2,2-dimethylpropane-1,3-diylbis(nitrilomethanylylidene)]diphenolato}molyb-denum(VI).

ABSTRACT: The asymmetric unit of the title compound, [Mo(C(19)H(16)Br(4)N(2)O(2))O(2)], comprises two mol-ecules. The coordination environments around the Mo(VI) atoms are distorted octa-hedral, defined by two oxide ligands and an N(2)O(2) donor set of the tetra-dentate Schiff base in each mol-ecule. The dihedral angles between the benzene rings in the mol-ecules are 76.2?(3) and 77.7?(3)°. An inter-esting feature of the crystal structure is the presence of Br?Br contacts [3.4407?(11), 3.5430?(11) and 3.6492?(10)?Å], which are shorter than the sum of the van der Waals radius of Br atoms (3.70?Å). The crystal structure is further stabilized by inter-molcular C-H?Br and C-H?? inter-actions. The crystal under investigation was twinned by nonmerohedry in a 0.053?(1):0.947?(1) ratio.

(4,4',6,6'-Tetra-tert-butyl-2,2'-{[2-(di-methyl-amino)-ethyl]-nitrilo-bis-(methyl-ene)}diphenolato)dioxidomolyb-denum(VI) chloro-form monosolvate.

Project description:In the title compound, [Mo(C(34)H(54)N(2)O(2))O(2)]·CHCl(3), the molybdenum(VI) ion exhibits a cis-dioxide distorted octa-hedral geometry. Two anionic phenolate O-atom donors and two neutral N-atom donors of the ligand are trans and cis, respectively. The Mo=O bond lengths and the O=Mo=O bond angle are typical for six-coordinated dioxomolyb-denum(VI) complexes. The Mo-N bond lengths are longer than 2.30 Å, as expected for a trans O=Mo-N structure.

Project description:In the title complex, [Cu(C(23)H(28)N(2)O(4))]·H(2)O, the Cu(II) ion has a distorted planar geometry, coordinated by the N(2)O(2) unit of the tetra-dentate Schiff base ligand. The asymmetric unit comprises one complex mol-ecule and a water mol-ecule of crystallization. The water H atoms form bifurcated O-H?(O,O) 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.

In the crystal structure, mol-ecules are linked together by inter-molecular C-H?O inter-actions, forming extended chains along the a axis.

{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 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.
