The synthesis of the following mixed ligand complexes is reported: [Ni(phdtc)2(dpm)2], [Ni(phdtc)2(dpe)2], [Ni(phdtc)2(dpp)3], [Ni(1-naphdtc)2(dpm)2], [Ni(1-naphdtc)2], and [Ni(1-naphdtc)2(dpp)2], where phdtc = PhNHCSS-, 1-naphdtc = 1-NaPhNHCSS-, dpm = Ph2PCH2PPh2, dpe = Ph2P(CH2)2PPh2, and dpp = Ph2P(CH2)3PPh2. The complexes are characterised by microanalysis, IR and UV-Vis spectra, magnetic measurements, conductivity, X-ray powder diffraction, and thermal analysis. All the mixed ligand complexes are diamagnetic, and thus a square-planar or square-pyramidal (low-spin) structure was proposed for the present complexes.

Abstract The following mixed ligand complexes were synthesized and characterized: Co(Phdtcz)2(Phtu)2, Co(Phdtcz)2(Clphtu)2 , Co(Phdtcz)2(dtm), Ni(Et2dtc)2(dtm), Ni(Phdtc)2(dtm), Ni(p-Toluiddtc)2(dtm), Ni(α-naphdtc)2(dtm), and Ni(Phdtcz)(Et2dtc); where Phdtcz = phenyldithiocarbazate, Et2dtc = diethyldithiocarbamate, Phdtc = phenyldithiocarbamate, p-Toluiddtc = p-toluidinedithiocarbamate, α-naphdtc = α-naphthyldithiocarbamate, Phtu = phenylthiourea, Clphtu - chlorophenylthiourea, and dtm - bis(diphenylphosphinothioyl)-methane. Electronic and IR spectra, magnetic, conductivity and X-ray powder diffraction measurements were carried out. The Ni(II) and Co(II) complexes are suggested to be square planar and octahedral, respectively. The biological activity of the complexes was also tested.

The reaction of Cu(NO3)2·3H2O with 2,4′-oxybis(benzoic acid) and 4,4′-bipyridine under hydrothermal conditions produced a new mixed-ligand two-dimensional copper(II) coordination polymer, namely poly[[(μ-4,4′-bipyridine-κ2 N,N′)[μ-2,4′-oxybis(benzoato)-κ4 O 2,O 2′:O 4,O 4′]copper(II)] monohydrate], {[Cu(C14H8O5)(C10H8N2)]·H2O} n , which was characterized by elemental analysis, IR spectroscopy, thermogravimetric analysis and single-crystal X-ray diffraction. The X-ray diffraction crystal structure analysis reveals that the CuII ions are connected to form a two-dimensional wave-like network through 4,4′-bipyridine and 2,4′-oxybis(benzoate) ligands. The two-dimensional layers are expanded into a three-dimensional supramolecular structure through intermolecular O—H...O and C—H...O hydrogen bonds. Furthermore, magnetic susceptibility measurements indicate that the complex shows weak antiferromagnetic interactions between adjacent CuII ions.

The mixed ligand complexes of manganese(II), nickel(II), copper(II), zinc(II), and cadmium(II) involving aspartic acid and benzoic acid have been synthesized. The complexes were studied by various spectroscopic techniques such as infrared, electronic, X-ray diffraction, and magnetic measurements. The complexes were found to have octahedral geometry. The X-ray powder diffraction results show that the crystal systems of Mn(II)-Asp-Ben complex are hexagonal, and Ni(II)-Asp-Ben, Cu(II)-Asp-Ben, Zn(II)-Asp-Ben, and Cd(II)-Asp-Ben complexes are found to be triclinic. The value of unit-cell parameters and XRD data for the five mixed ligand complexes are reported.
