{2-[(2-Carbamothiol-ylhydrazin-1-yl-idene-κN,S)meth-yl]-6-hy-droxy-phenolato-κO}(triphenyl-phosphine-κP)nickel(II) chloride.

ABSTRACT: The deprotonated Schiff base ligand in the title compound, [Ni(C(8)H(8)N(3)O(2)S)(C(18)H(15)P)]Cl, functions as an N,O,S-chelating anion to the phosphine-coordinated Ni atom, which exists in a distorted square-planar geometry. The hy-droxy group forms an intra-molecular O-H⋯O hydrogen bond. The two amino groups of the cation are hydrogen-bond donors to the chloride anion; the hydrogen bonds generate a chain structure running along the b axis.

(Dithio-benzoato-κS,S')[hydridotris(pyrazol-1-yl-κN)borato](triphenyl-phosphine-κP)ruthenium(II).

Project description:Reaction of [Ru(Tp)Cl(PPh(3))(2)] (Tp = hydridotrispyrazolyl-borate) with ammonium dithio-benzoate in methanol leads to the formation of the title compound, [Ru(C(9)H(10)BN(6))(C(7)H(5)S(2))(C(18)H(15)P)]. In the crystal structure, the Ru atom is coordinated by three N atoms of the Tp ligand, one P atom of the triphenyl-phosphine ligand and the two S atoms of the dithio-benzoate ligand within a slightly distorted octa-hedron. The Ru-S bonds are slightly different [2.321 (1) and 2.396 (1) Å] and the average N-Ru-N angle is 86.31°.

Project description:In the crystal structure of the title compound, [Ru(C(4)H(6)BN(6))H(C(18)H(15)P)(2)(CO)]·C(2)H(3)N, discrete mononuclear complexes are found in which the Ru atom is coordinated by two triphenyl-phosphine (PPh(3)) ligands, one dihydro-bis(1,2,4-triazol-1-yl)borate ligand, one carbonyl ligand and one hydride atom within slightly distorted octa-hedra. The two P atoms of the PPh(3) ligands are trans positioned and the two N atoms of the chelating dihydro-bis(1,2,4-triazol-1-yl)borate ligand occupy cis positions.

(1,10-Phenanthroline-κN,N')(triphenyl-phosphine-κP)silver(I) trifluoro-methane-sulfonate.

Project description:The structure of the title complex, [Ag(C(12)H(8)N(2))(C(18)H(15)P)]CF(3)SO(3), is based on a distorted trigonal-planar N(2)P coordination of the Ag(I) ion, provided by two N atoms of the bidentate phenanthroline ligand and one P atom of the triphenyl-phosphine ligand. The phenanthroline ligand and one phenyl ring of the triphenyl-phosphine ligand almost lie in one plane (maximum deviation = 0.014 Å from the best planes). The crystal structure may be stabilized by an inter-molecular C-H⋯O hydrogen bond between the phenanthroline ligand and the O atom of the trifluoro-methane-sulfonate anion.

Redetermination of bis-(2-formyl-phenolato-κO,O')nickel(II) as bis-[2-(imino-meth-yl)phenolato-κN,O']nickel(II).

Project description:The crystal structure of bis-(2-formyl-phenolato-κ(2)O,O')nickel(II), [Ni(C(7)H(5)O(2))(2)], a square-planar centrosymmetric complex, has been reported previously [Li & Chen (2006). Acta Cryst. E62, m1038-m1039]. However, a number of warning signs allows the assumption that the carbonyl group in the salicylaldehydate ligand of the claimed complex is incorrect. The crystal structure was therefore redetermined on basis of the originally deposited structure factors. After substituting the carbonyl O atom by an N atom, the model can be completed with an imine H atom, which was clearly discernible in a difference map. The resulting model, corresponding to bis-[2-(imino-meth-yl)phenolato-κ(2)N,O']nickel(II), [Ni(C(7)H(6)NO)(2)], converges well and none of the previous structural alerts remains. This reinter-pretation is also consistent with the published synthesis, which was carried out using salicylaldehyde in the presence of aqueous NH(3). The reinter-preted structure is virtually identical to earlier reports dealing with this bis-iminato Ni(II) complex.

Bis{4-bromo-2-[(2-hy-droxy-eth-yl)imino-meth-yl]phenolato}nickel(II) monohydrate.

Project description:The title mononuclear nickel complex, [Ni(C(9)H(9)BrNO(2))(2)]·H(2)O, was obtained by the reaction of 5-bromo-salicyl-aldehyde, 2-amino-ethanol and nickel nitrate in methanol. The Ni(II) atom is six-coordinated by two phenolate O, two imine N and two hy-droxy O atoms from two crystallographically different Schiff base ligands, forming an octa-hedral geometry. In the crystal, mol-ecules are linked by inter-molecular O-H⋯O and O-H⋯Br hydrogen bonds, forming a three-dimensional network.

Bis[2-(hy-droxy-imino-meth-yl)phenolato]nickel(II): a second monoclinic polymorph.

Project description:The title compound, [Ni(C(7)H(6)NO(2))(2)], (I), is a second monoclinic polymorph of the compound, (II), reported by Srivastava et al. [Acta Cryst. (1967), 22, 922] and Mereiter [Private communication (2002) CCDC refcode NISALO01]. The bond lengths and angles are similar in both structures. The mol-ecule in both structures lies on a crystallographic inversion center and both have an inter-nal hydrogen bond. The title compound crystallizes in the space group P2(1)/c (Z = 2), whereas compound (II) is in the space group P2(1)/n (Z = 2) with a similar cell volume but different cell parameters. In both polymorphs, mol-ecules are arranged in the layers but in contrast to the previously published compound (II) where the dihedral angle between the layers is 86.3°, in the title polymorph the same dihedral angle is 29.4°. The structure of (I) is stabilized by strong intra-molecular O-H⋯O hydrogen bonding between the O-H group and the phenolate O atom.

Azido-(1,1-diphenyl-methanimine-κN)[hydridotris(pyrazolyl-κN)borato](triphenyl-phosphine-κP)ruthenium(II) diethyl ether solvate.

Project description:The reaction of [RuCl(C(9)H(10)BN(6))(C(18)H(15)P)(2)] with benzo-phenone imine in methanol, in the presence of sodium azide, leads to the formation of the title compound, [Ru(C(9)H(10)BN(6))(N(3))(HN=CPh(2))(C(18)H(15)P)]·C(4)H(10)O, which crystallizes as the diethyl ether solvate. In the crystal structure, the Ru atom is coordinated by three N atoms of one hydridotris(pyrazoly)borate anion, one P atom of one triphenyl-phosphine ligand, one N atom of the azide anion and one N atom of the benzophenone-imine ligand in a slightly distorted octa-hedral geometry. The azide anion is almost linear [177.0 (5)°], with an Ru-N-N angle of 125.9 (3)°. There is a small difference between the N-N distances [1.200 (5) and 1.164 (5) Å], the longer bond being adjacent to the Ru atom.
