In the title coordination polymer, {[Mn(C(12)H(14)O(4))(C(12)H(8)N(2))(H(2)O)]·H(2)O}(n), the Mn(II) atom has a highly distorted cis-MnN(2)O(4) octa-hedral geometry arising from its coordination by a bidentate phenanthroline ligand, a water mol-ecule and monodentate and bidentate adamantane-1,3-dicarboxyl-ate dianions. The bridging dianion leads to [001] chains in the crystal. The chains are li...

In the title mononuclear copper(II) compound, [Cu(C(2)O(4))(C(4)H(12)N(2)O)], the Cu(II) ion has a slightly distorted square-pyramidal geometry, with a tridentate N-(2-hydroxy-ethyl)ethyl-enediamine (HydEt-en) and a bidentate oxalate (ox) ligand. The N atoms of the HydEt-en ligand and the O atoms of ox ligand form the basal plane, while the O atom of the ethanol group of the HydEt-en ligand is ...

A series of homoleptic Ru(II) complexes including the tris-bidentate complexes of a new bidentate ligand 8-(1-pyrazol)-quinoline (Q1Pz) and bidentate 8-(3-pyrazol)-quinoline (Q3PzH), as well as the bis-tridentate complex of bis(quinolinyl)-1,3-pyrazole (DQPz) was studied. Together these complexes explore the orientation of the pyrazole relative to the quinoline. By examining the complexes struc...

2-Methoxyalkanols exhibit interesting variations with regard to equilibrium species of non hydrogen bonded, intramolecular hydrogen bonded and intermolecular hydrogen bonded forms [1-9]. 2-Methoxyethanol in particular has been found to behave as an anion as well as a bidentate ligand in its metal complexes [10-14], Trimethylsiloxyalkanols, Me3SiO(CH2)nOH synthesized through a simple way, are a ...

Bidentate phosphine ligands have been prepared on polystyrene beads modified with polyether dendron spacers. When complexed to Pd(0), these systems exhibited a negative dendritic effect on Heck catalysis (contrary to the analogous monodentate phosphine systems), but mostly a positive influence on carbonylation. This opposite influence of the dendronization falls into line with other differences...

In the title compound, [ReCl(C16H18N4)(CO)3], the Re(I) ion is coordinated in a distorted octa-hedral geometry by one Cl atom, two N atoms of the bidentate ligand and three carbonyl groups. The cyclo-hexane group is orientated in a transoid fashion with respect to the chloride ligand. In the crystal, N-H⋯Cl hydrogen bonds link complex mol-ecules, forming a two-dimensional network parallel to (1...

The title trinuclear ruthenium cluster, [Ru3(C30H24P2)(C9H11P)(CO)7(μ-H)2], has a triangular Ru3 core that is capped with a mesitylphosphin-idene ligand, μ3-PMes (Mes = mesityl = 2,4,6-tri-methyl-phen-yl). The 1,2-bis-(di-phenyl-phosphan-yl)benzene mol-ecule acts as a bidentate phosphine ligand via two P atoms connecting to a single Ru atom. The title compound crystallizes with two independent ...

In the title compound, [Ni(C(45)H(34)BN(6))(C(10)H(9)N(3))]Br·CH(2)Cl(2), the Ni(II) atom is five-coordinated by the tridentate hydro-tris-(3,5-diphenyl-pyrazol-yl)borate ligand and a bidentate di-2-pyridyl-amine ligand in a distorted square-pyramidal geometry. In the crystal, inter-molecular N-H⋯Br and C-H⋯Br hydrogen bonds link the Ni complex cations and the Br(-) ions, forming a chain along ...

The synthesis of novel mercury (II) complex with new ligands derived from Carbohydrazides has been reported. The complexes have general composition [ HgL2X2], Where L= Carbohydrazone and X = Cl-, NO3 . The ligand carbohydrazone behave as neutral bidentate Ligand through the carbonyl oxygen and azomethiene nitrogen. On the basis of elemental analysis, Electrochemical and spectroscopic studies, t...
