In the title compound, [Cu(C(15)H(11)N(3)O(3))(C(10)H(8)N(2))], the Cu(II) atom is five-coordinated in a distorted square-pyramidal CuN(3)O(2) geometry. The basal positions are occupied by three donor atoms from the tridentate Schiff base ligand and by one N atom from the 2,2'-bipyridine ligand. The axial position is occupied by the other N atom of the 2,2'-bipyridine ligand. The crystal struct...

In the title compound, [Zn(C(8)H(6)ClNO(4)S)(C(10)H(8)N(2))(H(2)O)], the Zn(II) atom is six-coordinated by two O atoms and one N atom from a tridentate Schiff base ligand and two N atoms from a chelating 2,2'-bipyridine ligand and one water mol-ecule, forming a slightly distorted octa-hedral geometry. In the crystal, O-H⋯O hydrogen bonds link pairs of complex mol-ecules into dimers. An intra-mo...

In the title compound, [Cu(C(11)H(11)NO(3))(C(11)H(16)N(4))]·H(2)O, the Cu(II) atom is five-coordinate in a distorted square-pyramidal geometry. The basal positions are occupied by three donor atoms from the tridentate Schiff base ligand and by one N atom from a bis-(3,5-dimethyl-prazol-l-yl)methane ligand. The apical position is occupied by the N atom of the other ligand of this type. There ar...

The Mo(VI) atom in the title complex, [Mo(C(11)H(13)N(3)OS)O(2)(C(2)H(6)OS)], is N,N',O-coordinated by the dianionic tridentate ligand, two mutually cis oxide O atoms and a dimethyl sulfoxide O atom, defining a distorted octa-hedral N(2)O(4) donor set. The most prominent feature of the crystal packing is the formation of inversion dimers via pairs of N-H⋯O hydrogen bonds and eight-membered {⋯HN...
