    ABSTRACT: The complete mol-ecule of the title complex, [Cu(3)(C(15)H(13)N(2)O(3))(2)(C(5)H(5)N)(2)], is generated by crystallographic twofold symmetry, with the central Cu atom lying on the rotation axis: it is coordinated by two N,O-bidentate ligands in a trans-CuN(2)O(2) distorted square-planar arrangement. The other Cu atom is coordinated by an N,O,O'-tridentate ligand and a pyridine mol-ecule in a distorted trans-CuN(2)O(2) arrangement. In the crystal structure, a C-H⋯π inter-action occurs.

    ABSTRACT: In the title dinuclear complex, [Cu(2)(C(19)H(11)N(3)O(3)S)(C(5)H(5)N)(2)], the two Cu(II) centers have different coordination environments, viz. N(2)OS and N(2)O(2), each exhibiting a distorted square-planar geometry. π-π inter-actions between the aromatic rings of neighbouring complexes [centroid-centroid distance = 3.856 (5) Å] link pairs of mol-ecules into centrosymmetric dimers, which are further packed into stacks along the b axis with relatively short Cu⋯Cu separations of 3.482 (1) Å. Weak inter-molecular C-H⋯N hydrogen bonds help to consolidate the crystal packing.

    ABSTRACT: There are two half-mol-ecules in the asymmetric unit of the title compound, [Cu(3)(C(13)H(9)N(2)O(3))(2)(C(5)H(5)N)(4)], and crystallographic inversion symmetry completes each trinuclear mol-ecule. In both mol-ecules, the central Cu atom (site symmetry ) adopts a distorted trans-CuO(2)N(4) octa-hedral geometry, arising from its coordination by two N,O-bidentate aroylhydrazine ligands and two pyridine mol-ecules. The peripheral Cu atoms adopt trans-CuN(2)O(2) square-planar coordinations arising from an N,O,O-tri-dentate ligand (that also bonds to the central Cu atom) and a pyridine mol-ecule.
