{6,6'-Dimeth-oxy-2,2'-[6-bromo-pyridine-2,3-diylbis(nitrilo-methyl-idyne)]-diphenol-ato}-copper(II) methanol solvate.

ABSTRACT: In the title compound, [Cu(C(21)H(16)BrN(3)O(4))]·CH(3)OH, the Cu(II) ion is coordinated by two N [Cu-N = 1.814?(3) and 1.917?(3)?Å] and two O [Cu-O = 1.805?(3) and 1.893?(3)?Å] atoms from the tetra-dentate Schiff base ligand in a distorted square-planar geometry. In the crystal structure, the approximately planar Cu complex mol-ecules are paired into centrosymmetric dimers with short inter-molecular Cu?N distances of 3.162?(3)?Å. Weak O---H...O hydrogen bonds may help to stabilize the structure.

Project description:The title Schiff base compound, C(21)H(26)N(2)O(4), exhibits two crystallographically independent mol-ecules in the asymmetric unit with similar conformations. The imino groups are coplanar with the benzene rings; the maximum deviations of the N atoms from the planes comprising the benzene rings and the imino groups are -0.037 (4), 0.013 (4), -0.021 (5), and 0.008 (5) Å. The dihedral angles between the benzene rings in the two mol-ecules are 53.64 (17) and 51.93 (17)°. Strong intra-molecular O-H⋯N hydrogen bonds generate S(6) ring motifs. The N atoms are also in close proximity to the H atoms of the dimethyl-propane groups, with H⋯N distances between 2.54 and 2.75 Å. The crystal structure is further stabilized by weak inter-molecular C-H⋯O hydrogen bonds, weak inter-molecular C-H⋯π inter-actions and π-π contacts involving the imine C atom and two C atoms from the adjacent benzene rings.

Project description:In the title compound, [Ni(C(22)H(17)BrN(2)O(4))]·CH(3)OH, the Ni(II) ion is in a slightly distorted square-planar geometry involving an N(2)O(2) atom set of the tetra-dentate Schiff base ligand.

The dihedral angle between the aromatic ring planes of the central aromatic ring and other two aromatic rings are 10.8?(3) and 6.0?(2)°. The crystal structure is stabilized by inter-molecular C-H?O and C-H?Br and by intra-molecular O-H?O hydrogen bonds.

Redetermination of 6,6'-dimeth-oxy-2,2'-[hexane-1,6-diylbis(nitrilo-dimethyl-idyne)]diphenol.

Project description:The title compound, C(22)H(28)N(2)O(4), contains two independent centrosymmetric mol-ecules (A and B). In the previous structure determination [Xia et al. (2007 ?). Acta Cryst. E63, o259] both A and B were modelled as neutral mol-ecules with the H atoms of the the O-H groups included in calculated positions. In this redetermination, the transferrable H atoms were located in difference maps and freely refined, indicating that one mol-ecule (A) crystallizes in the neutral (nonzwitterionic) form and the other in the zwitterionic form, namely 6,6'-dimeth-oxy-2,2'-[hexane-1,6-diylbis(nitrilo-dimethyl-idyne)]-di-phenol-6,6'-dimeth-oxy-2,2'-[hexane-1,6-diylbis(nitrilio-di-methyl-idyne)]diphenolate (1/1). This finding is supported by significant differences in the C-O(H) (A) and C-O(-) (B) bond lengths. In the crystal, the zwitterionic mol-ecules (B) are involved in inter-molecular N-H?O hydrogen bonds forming one-dimensional chains along [001]. Each independent mol-ecule forms an intra-molecular O-H?N (A) or N-H?O (B) hydrogen bond. In mol-ecule B, one of the -CH(2)- groups is disordered over two sets of sites with refined occupancies of 0.659?(8) and 0.341?(8).
