In the title three-dimensional coordination polymer, [Cd(N(3))(2)(C(8)H(10)N(4))](n), the coordination geometry around the Cd(II) atom is distorted octa-hedral. The Cd(II) atom is coordinated by two N atoms from two cis-positioned bridging 1,2-bis-(imidazol-1-yl)ethane (bime) ligands and four N atoms from four azide anions. Each azide ligand acts in an end-on bridging coordination mode. The azi...

A new dinuclear gold(I) complex, possessing a bridging diphosphine ligand (1,2-bis(diphenylphosphino)ethane) and two terminal thiol ligands (1-thioglycerol), was synthesized fully characterized by IR, 1H 31P NMR, fluorescence, ESI-mass, diffuse reflection spectroscopy, together with X-ray diffraction elemental analyses. The compound formed 1D chain supramolecular structure through intermolecula...

Dinuclear pentacoordinate nickel(ii) complexes of the formula [(NiTp*)2(μ-L)] (Tp* = hydrotris(3,5-dimethylpyrazolyl)borate; L = oxalate (); oxamate (); oxamidate (); OC(4-Cl-C6H4N)C(4-Cl-C6H4N)O ()) and {[Ni(N3-mc)]2(μ-L)}(PF6)2 (N3-mc = 2,4,4-trimethyl-1,5,9-triazacyclododec-1-ene; L = oxalate (); oxamate ()) have been synthesized and spectroscopically characterized (IR, (1)H NMR).

A series of homo- and heteronuclear ruthenium and osmium polypyridyl complexes with the bridging ligands 1,3-bis(5-(2-pyridyl)-1H-1,2,4-triazol-3-yl)benzene (H(2)mL) and 1,4-bis(5-(2-pyridyl)-1H-1,2,4-triazol-3-yl)benzene (H(2)pL) are reported. The photophysical properties of these compounds are investigated, and particular attention is paid to the heteronuclear (RuOs) compounds, which exhibit ...

In the title complex, [Cu(4)Cl(4)(C(58)H(52)N(2)P(4))](n), four Cu(II) atoms are held together via two doubly bridging and two triply bridging chlorides, forming a stair-like Cu(4)Cl(4) core having crystallographically imposed inversion symmetry, while the benzene-1,4-diamine ligand (with a crystallographic inversion center at the centroid) acts in a tetra-dentate coordination mode, bridging tw...

The title tetra-nuclear Cu(II) complex, [Cu(4)(C(12)H(12)N(2)O(2))(4)(CH(3)O)(4)(ClO(4))(2)](ClO(4))(2), is located around an inversion center. Each Cu(II) atom is coordinated by two cis-O atoms from two bridging methano-late anions and two cis-N atoms from two bridging 1,4-bis-(4,5-dihydro-1,3-oxazol-2-yl)benzene (L) ligands in the basal plane, and is further coordinated by one O atom of the b...

The first examples of lanthanide(III) organoarsonates, Ln(L(1))(H(2)O)(3) (Ln = La (1), H(3)L(1) = 4-hydroxy-3-nitrophenylarsonic acid), Ln(L(1))(H(2)O)(2) (Ln = Nd (2), Gd (3)), and mixed-ligand lanthanide(III) organoarsonates, Ln(2)(HL(1))(2)(C(2)O(4))(H(2)O)(2) (Ln = Nd (4), Sm (5), Eu (6)), were hydrothermally synthesized and structurally characterized. Compounds 1-3 feature a corrugated la...

The structures of the first two complexes with bidentate coordination aminoguanidine Schiff base, i.e., 2-acetylpyridine-aminoguanidine (L), are reported. complex formula [Cd2Cl6(HL)2] (1) was obtained in reaction warm aqueous solutions chloride salts Cd(II), Zn(II) and ligand, while cadmium bromide ligand presence deprotonating agent as well ammonium thiocyanate resulted formation which base h...

The reaction of one equivalent of 2-methyl-1-(pyridin-2-yl)propan-2-ol (HL) with two equivalents of [Ni(OAc)2·4H2O] in methanol afforded the nonanuclear coordination cluster [Ni9(HL-κ(2)N,O)4(OAc-κ(2)O)2(μ2-OAc-κ(1)O)2(μ2-OAc-κ(2)O,O')4(μ3-OAc-κ(2)O;κ(2)O,O')2(μ3-OMe)8] (1). All nickel ions are hexacoordinated and show a slightly distorted octahedral coordination geometry. This unusual centrosy...

The title trinuclear compound, [Cu3(C5H8NS2)Cl2(C6H15P)3], has the di-thio-carbamate ligand symmetrically chelating one CuI atom and each of the S atoms bridging to another CuI atom. Both chloride ligands are bridging, one being μ3- and the other μ2-bridging. Each Et3P ligand occupies a terminal position. Two of the CuI atoms exist within Cl2PS donor sets and the third is based on a ClPS2 donor...
