In the mononuclear title complex, [Mn(NCS)(2)(C(11)H(11)N(3)O)(4)], the Mn(II) atom, lying on an inversion center, is coordinated by two monodentate thio-cyanate anions and four monodentate 1-phenyl-3-(1H-1,2,4-triazol-1-yl)propan-1-one ligands in a distorted octa-hedral geometry. Each complex mol-ecule is linked to four neighboring ones by weak C-H⋯N and C-H⋯S hydrogen bonds, forming a two-dim...

In the title mononuclear complex, [Ni(C(4)H(5)O(2))(2)(C(10)H(9)N(3))]·1.5H(2)O, the Ni(II) ion is in a distorted square-planar coordination environment, formed by two O atoms from two methacrylate ligands and two N atoms from a bis-chelating dipyridylamine ligand. In the crystal structure, inter-molecular O-H⋯O and N-H⋯O hydrogen bonds link complex mol-ecules and water mol-ecules into one-dime...

In the title mononuclear complex, [Ag(C(18)H(18)N(2)P)(NO(3))(2)], the metal centre is coordinated in a slightly distorted trigonal-planar geometry by the P atom of the phosphine ligand and the O atoms of the two monodentate nitrate anions. In the crystal structure, complex mol-ecules are connected by inter-molecular N-H⋯O hydrogen bonds, forming chains running parallel to the b axis.

A chemoselective hydrosilylation method for aldehydes is developed using a ruthenium catalyst [(Ru(p-cymene)Cl2)2] and triethylsilane; a mono hydride bridged dinuclear complex [{(η(6)-p-cymene)RuCl}2(μ-H-μ-Cl)] and a Ru(iv) mononuclear dihydride complex [(η(6)-p-cymene)Ru(H)2(SiEt3)2] are identified as potential intermediates in the reaction and the proposed catalytic cycle involves a 1,3-hydri...

In the mononuclear title complex, [CoBr(2)(C(5)H(8)N(2))(2)], the Co(II) atom is coordinated by two N atoms from two monodentate 3,5-dimethyl-pyrazole ligands and two Br atoms in a highly distorted tetra-hedral geometry. In the crystal, the complex mol-ecules are linked by inter-molecular N-H⋯Br hydrogen bonds into chains along [101]. An intra-molecular N-H⋯Br hydrogen bond is also present.

Smoking causes a decrease of mitochondrial complex IV activity in chronic smokers. However, it is not known if this toxic effect is due to the acute effect of cigarette smoke itself or is a secondary phenomenon related to other smoking factors. The study assessed mitochondrial respiratory chain function in peripheral blood mononuclear cells of 15 healthy nonsmoker individuals before smoking (t0...

In the title complex, [Cd(C(6)H(4)NO(3))(2)(H(2)O)(4)], the Cd(II) atom is situated on a crystallographic centre of inversion. The Cd(II) atom shows a slightly distorted octa-hedral geometry and is coordinated by four O atoms from water mol-ecules and two O atoms from deprotonated carboxyl groups of nicotinic acid N-oxide ligands. The mononuclear complex mol-ecules are linked by O-H⋯O hydrogen ...

A mononuclear Fe(II) complex bearing 1-aminocyclopropane-1-carboxylic acid (ACCH) was synthesized and characterized. X-ray crystallography demonstrated that ACC binds to the Fe(II) ion in a bidentate mode constituting the first structural mimic of the expected binding of ACC to the Fe(II) center of the ethylene forming enzyme ACC-oxidase (ACCO). [Fe(BPMEN)ACC]SbF6 also constitutes a functional ...

The preparation and characterization of the new 3,5-diacetyl-1,2,4-triazol bis(4-cyclohexyl thiosemicarbazone) ligand, H(5)L(1), is described. Treatment of H(5)L(1) with K(2)PtCl(4) gave the dinuclear complex [Pt(H(3)L(1))](2), 1, but using MCl(2)(PPh(3))(2) where M = Pd or Pt, mononuclear complexes 2 and 3, of general formula [M(H(3)L(1))PPh(3)], were obtained. Subsequent reaction of the [Pd(H...
