Cyanidophenyl-tris(trimethyl-phosphine)cobalt(II).

ABSTRACT: The title mol-ecule, [Co(C(6)H(5))(CN)(C(3)H(9)P)(3)], lies on a crystallographic mirror plane with the Co(II) ion coordinated in a distorted square-pyramidal environment with one of the P atoms in the apical position. In the basal plane, the phenyl substituent is trans to the cyanide group with a C-Co-C angle which is significantly distorted from linearity.

Cyanidotetra-kis-(trimethyl-phosphine)cobalt(I).

Project description:The title compound, [Co(CN)(C(3)H(9)P)(4)], was obtained as a product of the reaction of [Co(PMe(3))(4)] with a molar equivalent of 2,6-difluoro-benzonitrile in diethyl ether. This compound is stable in the air for several hours, but rapidly decomposes at room temperature in solution. The cobalt(I) atom has s trigonal-bipyramidal coordination enviroment in which the cyano group and one of the PMe(3) groups are in the axial positions.

Dichloridotris(trimethyl-phosphine)nickel(II).

Project description:The title compound, [NiCl(2)(C(3)H(9)P)(3)], was obtained as a product of the reaction of [NiCl(2)(PMe(3))(2)] with an equivalent trimethyl-phosphine in diethyl ether. It easily loses trimethyl-phosphine at room temperature to give NiCl(2)(PMe(3))(2). There are two independent mol-ecules in the asymmetric unit, and their bond lengths and angles are similar. The Ni environment is trigonal bipyramidal. One Ni, one P and two Cl atoms lie in the equatorial plane, with the remaining two P atoms occupying axial positions. The equatorial Ni-P bond length is shorter than the axial bond lengths.

[2,6-Bis(diphenyl-phosphino-oxy)phen-yl]bis-(trimethyl-phosphine)cobalt(I).

Project description:The title compound, [Co(C(30)H(23)O(2)P(2))(C(3)H(9)P)(2)], was synthesized by the addition of a Co(PMe(3))(4) solution to (PPh(2)O)(2)C(6)H(4). The Co(I) atom displays a trigonal-bipyramidal geometry with the two P atoms of the 'PCP' pincer ligand and the P atom of one of the trimethyl phosphine ligands forming the basal plane, whereas the metalated C atom and the P atom of the second phospine ligand occupy the apical sites. The Co-C distance is 1.961?(2)?Å and the C-Co-P angle is 171.96?(6)°.

Tris(ethyl-enediamine)cobalt(II) sulfate.

Project description:The structure of the title compound, [Co(II)(C(2)H(8)N(2))(3)]SO(4), the cobalt example of [M(C(2)H(8)N(2))(3)]SO(4), is reported. The Co and S atoms are located at the 2d and 2c Wyckoff sites (point symmetry 32), respectively. The Co atom is coordinated by six N atoms of three chelating ethyl-enediamine mol-ecules generated from half of the ethyl-enediamine mol-ecule in the asymmetric unit. The O atoms of the sulfate anion are disordered mostly over two crystallographic sites. The third disorder site of O (site symmetry 3) has a site occupancy approaching zero. The H atoms of the ethyl-enediamine mol-ecules inter-act with the sulfate anions via inter-molecular N-H?O hydrogen-bonding inter-actions.

Dichloridobis(3,4,5-trimethyl-1H-pyrazole-κN)cobalt(II).

Project description:In the title compound, [Co(II)Cl(2)(C(6)H(10)N(2))(2)], a pair of 3,4,5-trimethyl-pyrazoles act as monodentate ligands. Two Cl(-) anions are also bonded directly to the Co(II) atom, which has a CoN(2)Cl(2) chromophore in a slightly distorted tetra-hedral geometry. The two mol-ecules in the asymmetric unit are related by an approximate twofold rotation roughly parallel to the a axis. The amino H atom in the pyrazole ring participates in weak N-H⋯Cl hydrogen bonds to form chains that propagate roughly parallel to the c axis.

Tris(ethyl-enedi-amine)-cobalt(II) dichloride.

Project description:The title compound, [Co(II)(C2H8N2)3]Cl2, was obtained unexpectedly as the product of an attempted solvothermal synthesis of cobalt selenide from the elements in the presence of NH4Cl in ethyl-enedi-amine solvent. The three chelate rings of the distorted octa-hedral [Co(C2H8N2)3](2+) complex cation adopt twisted conformations about their C-C bonds. The spread of cis-N-Co-N bond angles [80.17 (6)-98.10 (6)°] in the title compound is considerably greater than the equivalent data for [Co(III)(C2H8N2)3]Cl3 [Takamizawa et al. (2008 ▶). Angew. Chem. Int. Ed. 47, 1689-1692]. In the crystal, the components are linked by numerous N-H⋯Cl hydrogen bonds, generating a three-dimensional network in which the cationic complexes are stacked in columns along [010] and separated by columns of chloride anions.

trans-Dichloridobis[tris-(2-methoxy-phen-yl)phosphine]palladium(II).

Project description:The structure of the title compound, [PdCl(2)(C(21)H(21)O(3)P)(2)], shows a nearly square-planar geometry for the Pd(II) atom within the Cl(2)Pd[P(PhOMe)(3)](2) ligand set. The Pd(II) atom sits on a centre of inversion and therefore the asymmetric unit contains one half-mol-ecule, i.e. half of one Pd(II) atom, one Cl atom and one tris-(2-methoxy-phen-yl)phosphine ligand.

Project description:In the title compound, [PdBr(2)(C(18)H(12)Cl(3)P)(2)], the Pd(II) ion is situated on a centre of symmetry and is coordinated by two Br anions [Pd-Br = 2.4252 (2) Å] and two P-donor ligands [Pd-P = 2.3317 (6) Å] in a slightly distorted square-planar geometry [P-Pd-Br = 86.589 (15)°].

Tuning Cobalt(II) Phosphine Complexes to be Axially Ambivalent.

Project description:We report the isolation and characterization of a series of three cobalt(II) bis(phosphine) complexes with varying numbers of coordinated solvent ligands in the axial position. X-ray quality crystals of [Co(dppv)2][BF4]2 (1), [Co(dppv)2(NCCH3)][BPh4]2 (2), and [Co(dppv)2(NCCH3)2][BF4]2 (3) (dppv = cis-1,2-bis(diphenylphosphino)ethylene) were grown under slightly different conditions, and their structures were compared. This analysis revealed multiple crystallization motifs for divalent cobalt(II) complexes with the same set of phosphine ligands. Notably, the 4-coordinate complex 1 is a rare example of a square-planar cobalt(II) complex, the first crystallographically characterized square-planar Co(II) complex containing only neutral, bidentate ligands. Characterization of the different axial geometries via EPR and UV-visible spectroscopies showed that there is a very shallow energy landscape for axial ligation. Ligand field angular overlap model calculations support this conclusion, and we provide a strategy for tuning other ligands to be axially labile on a phosphine scaffold. This methodology is proposed to be used for designing cobalt phosphine catalysts for a variety of oxidation and reduction reactions.
