In the title salt, (C(5)H(14)N(2))[FeCl(4)(H(2)O)(2)], the Fe(II) cation is coordinated by four Cl(-) anions and two water mol-ecules in a distorted octa-hedral geometry. The piperazine ring adopts a normal chair conformation. Inter-molecular N-H⋯Cl, N-H⋯(Cl,Cl) and O-H⋯Cl hydrogen bonding is present in the crystal structure.

The reaction of isophthaloyl dichloride with 1H-1,2,4-triazole afforded the new ligand 1,3-phenylenebis(1,2,4-triazole-1-yl)methanone (1). A series of Co(II), Cu(II), Zn(II) and Ni(II) complexes were synthesized using 1 and then characterized by melting point analysis, elemental analysis, theoretical calculations, thermogravimetric analysis, X-ray powder diffraction, nuclear magnetic resonance,...

In the neutral title complex, [HgCl(2)(C(12)H(11)NO(3))], the Hg(II) ion is penta-coordinated by two Cl atoms, one N atom and two weakly coordinating O atoms from the methyl 2-(quinolin-8-yl-oxy)acetate ligand. The coordination around the Hg(II) ion may be described as highly distorted trigonal-bipyramidal. Centrosymmetric dimers are formed by an additional weak Hg⋯Cl inter-action, leading to a...

The centrosymmetric dinuclear title compound, [Zn(2)Cl(4)(C(4)H(12)N(2))(2)], is isostructural with its previously reported Cu(II) analogue [Phelps, Goodman & Hodgson (1976 ▶). Inorg. Chem.15, 2266-2270]. In the title compound, each of the Zn(II) ions is coordinated by two N atoms from a chelating N,N-dimethyl-ethylenediamine ligand, two bridging Cl atoms and one terminal Cl atom. The coordinat...

The title compound, [Cu(2)(C(7)H(6)N(2)O(3))Cl(2)(C(5)H(5)N)(4)]·C(3)H(8)O, is a binuclear pyrazolate complex, in which the two Cu(II) atoms have different coordination numbers and are connected by a bridging Cl atom. One Cu(II) atom has a distorted square-pyramidal coordination environment formed by two pyridine N atoms, one bridging Cl atom and an N,O-chelating pyrazolate ligand. The other Cu...

The asymmetric unit of the crystal structure of the title compound, [Cd(2)Cl(4)(C(5)H(8)N(2))(3)](n), contains two Cd(II) cations, three 1-ethyl-1H-imidazole ligands, and four Cl(-) anions. The two Cd(II) atoms have quite different coordination environments: one is octa-hedrally coordinated by four Cl atoms and two N atoms from two 1-ethyl-1H-imidazole ligands, and the second is in a severely d...

In the title compound, [Fe(II)(C44H24Cl4N4)(C6H5CH2NH2)2]·C6H14 or [Fe(II)(TPP-Cl)(BzNH2)2]·n-hexane [where TPP-Cl and BzNH2 are 5,10,15,20-tetra-kis-(4-chloro-phen-yl)porphyrinate and benzyl-amine ligands, respectively], the Fe(II) cation lies on an inversion centre and is octa-hedrally coordinated by the four pyrrole N atoms of the porphyrin ligand in the equatorial plane and by two amine N a...

The reaction between [Ru 2 Cl ( my -Cl) (CO) 6 ] and the biradicaloid [P( -NTer)] proceeds under insertion of a Ru(II)Cl(CO) fragment into one P-N bond addition chloride to adjacent phosphorus center. Thereby an unprecedented ruthenacycle is obtained that was investigated by single crystal X-ray analysis, NMR IR spectroscopy DFT calculations. reactivity complex in halide-pseudo-halide exchange ...
