4,4',6,6'-Tetra-tert-butyl-2,2'-[1,2-phenyl-enebis(nitrilo-methyl-idyne)]diphenol acetone solvate.

ABSTRACT: In the Schiff base mol-ecule of the title compound, C(36)H(48)N(2)O(2)·C(3)H(6)O, the central benzene ring makes dihedral angles of 46.64?(10) and 49.34?(10)° with the two outer benzene rings, and the two outer benzene rings form an angle of 39.13?(8)°. There are two intra-molecular O-H?N hydrogen bonds involving the two hydr-oxy groups, which generate S(6) ring motifs. In the crystal structure, the Schiff base mol-ecules are linked into a chain along the a axis by C-H?? inter-actions. The acetone solvent mol-ecules are attached to the chain via C-H?O hydrogen bonds.

Project description:The mol-ecule of the title compound, [Zn(C(28)H(30)N(2)O(2))(CH(3)COCH(3))], lies across a mirror plane with the Zn(II) ion and the acetone mol-ecule on the mirror plane.

The central benzene ring makes a dihedral angle of 16.5 (2)° with the two outer phenolate rings. In the crystal structure, the mol-ecules are arranged into anti-parallel columns along the a axis.

6,6'-Dimeth-oxy-2,2'-[4,5-dimethyl-o-phenyl-enebis(nitrilo-methyl-idyne)]diphenol monohydrate.

Project description:In the title compound, C(24)H(24)N(2)O(4)·H(2)O, the dihedral angles between the central benzene ring and the two outer benzene rings of the Schiff base are 65.06?(9) and 3.02?(9)°. Strong intra-molecular O-H?N hydrogen bonds generate S(6) ring motifs. The H atoms of the water mol-ecule act as donors in the formation of bifurcated O-H?(O,O) inter-molecular hydrogen bonds with the O atoms of the hydr-oxy and meth-oxy groups with R(1) (2)(5) ring motifs; these may influence the mol-ecular conformation.

Chlorido{4,4',6,6'-tetra-tert-butyl-2,2'-[o-phenyl-enebis(nitrilo-methyl-idyne)]diphenolato-?O,N,N',O'}manganese(III).

Project description:The asymmetric unit of the title Schiff base complex, [Mn(C(36)H(46)N(2)O(2))Cl], comprises two crystallographically independent mol-ecules. The Mn(III) centre in each mol-ecule adopts a distorted square-pyramidal geometry. Each Mn(III) ion is coordinated by the N(2)O(2) atoms of the tetra-dentate Schiff base ligand forming the basal plane and the coordinated chloride anion occupies the apical position. Four bifurcated intra-molecular C-H?O contacts stabilize the mol-ecular structure. In the crystal packing, mol-ecules are linked into dimers via inter-molecular C-H?Cl contacts and further stabilized by C-H?? inter-actions. The crystal studied was a non-merohedral twin, the refined ratio of the twin components being 0.441?(1):0.559?(1).

The cocrystal aqua-chlorido{6,6'-di-tert-butyl-2,2'-[1,2-phenyl-enebis(nitrilo-methyl-idyne)]diphenolato-κO,N,N',O'}-manganese(III)-chlorido{6,6'-di-tert-butyl-2,2'-[1,2-phenyl-enebis(nitrilo-methyl-idyne)]diphenolato-κO,N,N',O'}(methanol-κO)manganese(III) (1/1).

Project description:The asymmetric unit of the title complex, [Mn(C(28)H(30)N(2)O(2))Cl(H(2)O)][Mn(C(28)H(30)N(2)O(2))Cl(CH(3)OH)], contains two discrete Mn(III) complexes of a Schiff base ligand, with an N(2)O(2) donor set. Both Mn(III) centers are in a distorted octa-hedral geometry with the N(2)O(2) donor atoms of the tetra-dentate Schiff base dianion in the equatorial plane. The axial positions in the coordination environment of one Mn(III) complex are occupied by a chloride ion and a water mol-ecule, but a methanol mol-ecule replaces the water mol-ecule in the other complex. The coordinated water mol-ecule takes part in an O-H⋯Cl hydrogen bond between the two Mn(III) complexes. In the crystal structure, O-H⋯Cl hydrogen bonds link the mol-ecules into infinite one-dimensional chains along the [100] direction. The crystal structure is stabilized by O-H⋯Cl hydrogen bonds together with weak C-H⋯O and C-H⋯Cl inter-actions. A C-H⋯π inter-action is also observed in the crystal structure.
