The crystal structure of the title compound, (C(4)H(12)N(2))(2)[BiCl(6)]Cl·H(2)O, consists of piperazinediium cations, [BiCl(6)](3-) anions, Cl(-) anions and uncoordinated water mol-ecules. The Bi(III) cation is coordinated by six Cl(-) anions in a slightly distorted octa-hedral geometry. The diprotonated piperazine ring adopts a chair conformation. In the crystal, extensive inter-molecular N-H...

In the title compound, [RhCl(3)(C(12)H(12)N(2)O)]·CH(2)Cl(2), the Rh(III) atom shows a slightly distorted octa-hedral geometry being coordinated by two N atoms and one O atom from the 2,2'-(oxydimethanedi-yl)dipyridine ligand and three Cl atoms. Two Cl atoms adopt a trans arrangement to the two pyridyl N atoms, while the third Cl atom and the O atoms occupy the axial site. The Rh-Cl bonds that ...

The title compound, [Cr(2)Cl(2)O(C(18)H(18)N(4))(2)](PF(6))(2), is isostructural with the V(III) analogue. Each Cr(III) atom is chelated by the tetra-dentate tris-(2-pyridylmeth-yl)amine ligand via four N atoms, and further coordinated by one Cl atom and one bridging O atom, giving a slightly distorted octa-hedral coordination geometry. The dinuclear complex is centrosymmetric, with the bridgin...

The assignments structures of the four 1:1 pipemidic acid (pipH)–magnesium(II), calcium(II), zinc(II), and iron(III) complexes, [Mg(pip)(H2O)3(Cl)].6H2O, [Ca(pip)(H2O)3(Cl)].2H2O, [Zn(pip)(H2O)3(Cl)].4H2O, [Fe(pip)(H2O)2(Cl)2].6H2O, (where pip = deprotonated pipemidic), were synthesized through chemical reactions MgCl2.6H2O, CaCl2.2H2O, ZnCl2, FeCl3.6H2O metal salt chlorides with pipH chemother...

The title compound, [Fe(C(14)H(14)N(3)O(2))Cl(2)]·[ZnCl(2)(C(14)H(15)N(3)O(2))], is formulated as [Fe(III)(bpg)Cl(2)][Zn(II)Cl(2)(bpgH)], where bpg is the tetra-dentate ligand N,N-bis-(2-pyridylmeth-yl)glycine. The structure contains one crystallographically distinct complex with Fe(III) and Zn(II) atoms present in a 50:50 ratio in a single-atom site. The non-coordinated O atoms of the carboxyl...

Reaction of [TiCp*Cl3] (Cp*=η5-C5Me5) with one equivalent magnesium in tetrahydrofuran at room temperature affords the paramagnetic trinuclear complex [{TiCp*(μ-Cl)}3(μ3-Cl)], which reacts dinitrogen under ambient conditions to give diamagnetic derivative [{TiCp*(μ-Cl)}3(μ3-η1 : η2 η2-N2)] and titanium(III) dimer [{TiCp*Cl(μ-Cl)}2]. The structure mixed-valence complexes has been studied by expe...

A detailed catalytic study of LFe(III)Cl (where L = 3-{2-[2-(3-hydroxy-1,3-diphenyl-allylideneamino)-ethylamino]-ethylimino}-1,3-diphenyl-propen-1-ol) for hydrocarbon oxidation was carried out, focusing on the role of solvent, atmospheric dioxygen, and oxidant on catalytic efficiency. The data showed that LFe(III)Cl catalyst was efficient in homogeneous hydrocarbon oxidations providing signific...

Two half-sandwich iridium(III) and rhodium(III) complexes with 11H-indeno[1,2-b]quinoxalin-11-one oxime (IQ-1) ligand were prepared by the reaction of proligand [M(Cp*)Cl2]2 (M = Ir, Rh) dimers. The between IQ-1 [Ir(Cp*)Cl2]2 in methanol gave complex [Ir(Cp*)(IQ-1)Cl] (1), which crystallized a centrosymmetric space group as true racemate. Whereas [Rh(Cp*)(IQ-1)Cl] (2) form racemic conglomerate ...
