“…The Cu(II)-thiocyanato complex 1 derived from the linear tridentate amine ligands Me 3 dpt and Mepea [30] (2), and this finding is in complete agreement with previous results for complexes derived from Gly, Medpt, and Et 2 dien [7,8,34]. In general, increasing the steric hindrance at the terminal coordinated …”

Two thiocyanato-Cu(II) complexes including mononuclear dithiocyanato Cu(Me 3 dpt)(NCS) 2 (1) and the polymeric 1D [Cu(D,L-Ala)(l N,S -NCS)(H 2 O)] n (2) were synthesized and structurally characterized (Me 3 dpt = bis(N-methyl-3-propyl)methylamine, Ala = alaninate anion). The IR spectrum of complex 1 confirmed the N-bonding coordination mode of the thiocyanate groups, and its visible spectrum revealed the square pyramidal geometry around the central Cu 2? ion. Single X-ray crystallography of 1 showed that the Cu(II) center displays square pyramidal geometry with severe distortion toward trigonal bipyramidal environment. Complex 2 forms a 1-D polymeric chain with the NCS -acting as a l N,S -ligand. A distorted SP geometry around the Cu 2? centers was achieved by the O and N atoms of alaninato anion, the aqua ligand and by the N and S atoms of the bridging thiocyanate groups. Hydrogen bonds of the type N-HÁÁÁO, N-HÁÁÁS and O-HÁÁÁO are formed in this complex leading to the extension of the 1D chain to a supramolecular network.

The title neutral copper complex, [Cu2Cl4(C8H17N3O2)2], shows a binuclear center with a Cu—(μ-Cl)2—Cu core, in which each copper ion is coordinated by the N,N,O donor atoms of the tridentate ligand 1,4,6-trimethyl-6-nitro-1,4-diazepine (meaaz-NO2) and three chloride exogenous ligands. Each metal ion is facially coordinated by meaaz-NO2 through N,N,O donor atoms, whereas two bridging and one terminal chloride ions occupy the other face of the highly Jahn–Teller-distorted octahedron. Two N atoms from tertiary amine groups of the meaaz-NO2 ligand and two exogenous Cl atoms with short Cu—N and Cu—Cl distances define the equatorial plane. The coordination around each CuII ion is completed by another Cl atom and an O atom from the NO2 group, in the axial positions. The binuclear complex exhibits a centrosymmetric structure with point symmetry .
