چکیده
In the title complex, [Ni(C(22)H(16)Br(2)N(2)O(4))], the Ni(II) ion is coordinated by two N atoms and two O atoms of a tetra-dentate Schiff base ligand, forming a slightly distorted square-planar coordination environment. The dihedral angle between the two bromo-substituted benzene rings is 10.1 (3)°.

In the title complex, [Co(C(22)H(18)N(2)O(4))(CN)(H(2)O)]·0.5CH(3)CN, the Co(III) cation is N,N',O,O'-chelated by a 6,6'-dimeth-oxy-2,2'-[1,2-phenyl-enebis(nitrilo-methanylyl-idene)]diphenolate dianion, and is further coordinated by a cyanide anion and a water mol-ecule in the axial sites, completing a distorted octa-hedral coordination geometry. In the crystal, pairs of bifurcated O-H⋯(O,O) hy...

The asymmetric unit of the title compound, [Ni(C(17)H(12)I(4)N(2)O(2))], comprises half of a Schiff base complex. The Ni(II) and central C atom of the propyl chain are located on a twofold rotation axis. The geometry around the Ni(II) atom is square planar, supported by the N(2)O(2) donor atoms of the coordinated ligand. In the crystal, there are no significant inter-molecular inter-actions pre...

In the title mol-ecule, C(30)H(36)N(2)O(2), the dihedral angles between the central benzene ring and the two benzene rings of the butyl-salicylaldimine groups are 14.3 (2) and 40.6 (2)°. There are two strong intra-molecular O-H⋯N hydrogen bonds which form S(6) rings. The crystal studied was a non-merohedral twin with refined components of 0.270 (4) and 0.730 (4).

In the title complex, [Co(C(22)H(18)N(2)O(4))(CN)(H(2)O)]·CH(3)CN, the Co(III) ion is six-coordinated in a distorted octa-hedral environment defined by two N atoms and two O atoms from a salen ligand in the equatorial plane and one O atom from a water mol-ecule and one C atom from a cyanide group at the axial positions. O-H⋯O hydrogen bonds connect adjacent complex mol-ecules into dimers. C-H⋯N...

In the title compound, [Ni(C(18)H(18)N(2)O(4))]·C(3)H(7)NO, the central Ni(II) atom is in a square-planar O(2)N(2) coordination environment. The planar Ni-salen moieties (r.m.s. deviation for the plane through the conjugated part of the Ni-salen group = 0.07 Å) form parallel stacks in the a-axis direction, with alternating Ni⋯Ni separations of 3.5339 (7) and 3.6165 (7) Å. In the crystal, there ...
