The title compound, [Mo(C5H5)(C2H3O)(C12H9O3P)(CO)2], was prepared by reaction of [Mo(C5H5)(CO)3(CH3)] with tris-(furan-2-yl)phosphane. The Mo(II) atom exhibits a four-legged piano-stool coordination geometry with the acetyl and phosphine ligands trans to each other. The O atom of the acetyl ligand points down, away from the Cp ring. In the crystal, mol-ecules form centrosymmetrical dimers via ...
In the structure of the title compound, [Pd(C(19)H(21)N(2)P)(2)](PF(6))(2)·2.85CH(3)CN, the two six-membered NHC-phosphane chelate rings form a distorted square-planar coordination geometry around the Pd(II) atom, which lies 0.212 (1) Å above the coordination plane. The sum of the bond angles at Pd(II) is 358.3°, with C-Pd-P bite angles of 84.03 (10) and 83.54 (9)°. The structure includes three...
In the title compound, [AgCl(C7H7N3O2S)(C18H15P)2], the AgI ion is in a distorted tetra-hedral coordination environment formed by P atoms from two tri-phenyl-phosphane ligands, one terminal S atom from the 1-(4-nitro-phen-yl)thio-urea ligand and a chloride ion. In the crystal, bifurcated (N-H)2⋯Cl hydrogen bonds [with graph-set motif R21(6)] connect complex mol-ecules, forming zigzag chains alo...
The Ni(II) atom in the title complex, [Ni(C(13)H(8)BrNOS)(C(18)H(15)P)], is coordinated by the N, O and S atoms of the dianionic tridentate ligand, and its square-planar geometry is completed by a phosphane P atom. The dihedral angle between the aromatic rings in the 4-bromo-2-[(2-sulfido-phen-yl)imino-meth-yl]phenolate ligand is 2.01 (14)°. The most prominent feature of the packing is the pres...
In the title compound, [Rh(C(5)H(7)O(2))(C(18)H(14)BrP)(CO)], the Rh(I) atom adopts a slightly distorted square-planar geometry involving two O atoms [Rh-O = 2.077 (2) and 2.033 (2) Å] of the acetyl-acetonate ligand, one carbonyl C atom [Rh-C = 1.813 (2) Å] and one P atom [Rh-P = 2.242 (5) Å] of the PPh(2)(2-BrC(6)H(4)) phosphane ligand. Difference electron density maps indicate a disorder of t...
In the title compound, [CuI(C(8)H(8)N(2)S)(C(18)H(15)P)(2)]·CH(3)OH, the coordination environment around the Cu(I) atom is distorted tetra-hedral, defined by two P atoms of two triphenyl-phosphane ligands, one S atom of a 5-methyl-1H-benzimidazole-2(3H)-thione ligand and one I atom. The complex mol-ecules and the methanol solvent mol-ecules are connected via N-H⋯O and O-H⋯I hydrogen bonds, form...
Single crystals of the title compound, (imidazolium-2-yl)phenyl-phosphinate monohydrate, C(9)H(9)N(2)O(2)·H(2)O, were ob-tained from methanol/water after deprotection and oxidation of bis-(1-diethoxy-methyl-imidazol-2-yl)phenyl-phosphane. In the structure, several N-H⋯O and P-O⋯H-O hydrogen bonds are found. π-π inter-actions between the protonated imidazolyl rings [centroid-centroid distance = ...
The well known title compound, trans-[Mo(C18H15P)2(CO)4], has not been studied previously by X-ray crystallography, unlike its cis isomer. The complex possesses crystallographically imposed inversion symmetry, with the Mo atom residing on an inversion centre (1a Wyckoff position). The two tri-phenyl-phosphane groups are arranged in a staggered orientation. Each of the phenyl groups exhibits sig...
