The crystal structures of two mono(dpyam)copper(II) complexes, [Cu(dpyam)(NO2)2] (1) and [Cu(dpyam)(H2O)2(SO4)] (2) and two dithiocyanate compounds containing bis(dpyam)copper(II) units, [Cu(dpyam)2(NCS)](SCN)·0.5DMSO (3) and [Cu(d- pyam)2(SCN)2] (4) have been determined by X-ray crystallography. The second orthorhombic form of the monomeric Cu(II) complex 1 was obtained by the reaction of di-2-pyridylamine (dpyam) with CuCl and NaNO2 in water-methanol solution. Each copper(II) ion in 1 exhibits a tetrahedrally-distorted square base of the CuN2O2 chromophore, with off-the-z-axis coordinated nitrito groups weakly bound in approximately axial positions. Complex 2 is an example of a polymeric copper(II) derivative containing the bidentate bridging sulfate ligand in the long-bonded axial positions. Each copper(II) ion in 2 shows an elongated tetragonal octahedral stereochemistry. The CuN4N? chromophore of 3 involves a square-based pyramidal structure, slightly distorted towards a trigonal bipyramidal stereochemistry, tau = 0.13. One of the SCN- anions is bonded to the copper(II) ion via the N atom in the axial position of the square pyramid. Complex 4 is centrosymmetric and octahedrally elongated, with the SCN- anions coordinating in axial positions via the S atom. The structures of complexes 1-4 and their ESR and electronic reflectance spectra are compared with those of related complexes.

Under different situations, solvothermal reactions of 3,5-diethyl-4-(4- pyridyl)-pyrazole (HL) with CuX or CuX2 (X = Cl, Br, I, and SCN) afforded five copper(I) coordination polymers, {CuX[CuL]3· solvent}n (X = Cl, 1; Br, 2; I, 3; X = SCN and solvent = MeCN, 4) and {Cu2I2[CuL]3}n (5). X-ray diffraction analyses show that all the complexes have trinuclear [CuL] 3 (referred as Cu3) secondary building units featuring planar nine-membered Cu3N6 metallocycles with three peripheral pyridyl groups as connectors, which are further linked by CuX or Cu2X2 motifs to generate single- or double-strand chains. Interestingly, the Cu(I) atoms within the Cu3 units in 1-5 behave as coordinatively unsaturated pi-acid centers to contact soft halide/pseudohalide X atoms of CuX and Cu2X2 motifs, which lead to novel sandwich substructures of [(Cu3)(Cu2X2)(Cu 3)] (X = Br, I, and SCN) in 2-4. In addition, both the pi-acid [Cu3]···X contacts and intertrimer Cu···Cu interactions contribute to the one-dimensional (1D) double-strand and 2D/3D supramolecular structures of 1-5. All of these complexes exhibit high thermostability and bright solid-state phosphorescence upon exposure to UV radiation at room temperature. The emissions arise from the mixtures of metal-centered charge transfer, metal to ligand charge transfer, and halide-to-ligand charge transfer excited states, and can be tuned by intermolecular pi-acid [Cu3]···halide/ pseudohalide contacts.

Controllable synthesis of uniformly disk-shaped CuS nanostructures with a narrow size distribution was realized by a lowerature (150 C) solvothermal process using polyvinyl pyrrolidone (PVP) as the surfactant. Monodispersed nanodisks of pure CuS phase with an average diameter of ca. 500 nm could be obtained at a specific S/Cu molar ratio (xS/Cu) of raw materials, which was revealed to affect the phase structure and morphology of the product but the influence of PVP content (xPVP) is limited. The CuS nanodisks have a broad absorption in the visible region and superior photocatalytic performances for the degradation of RhB whose decomposition rate reaches 93% in 2 h, indicating a potential application in the field of wastewater treatment.

The influence of the central ion to ligand mole ratio on the course of complex formation is examined in reaction of L with copper(II) chloride. In Cu(II):L mole ratio of 1:1, in methanolic solution the reaction yields to yellow-green Cu2L 2Cl4 crystals. In the filtrate a thermodynamically more stable orange Cu2L2Cl2 copper(I) complex is forming. With a Cu(II):L mole ratio of 1:2 only the latter compound is obtained. The composition and the structure of the compounds have been determined on the basis of customary methods. On the basis of FTIR spectrum of the intermediate which is forming during the thermal decomposition of Cu2L 2Cl2 a decomposition mechanism is proposed.
