L design is regarded as an important area in the development of efficient, profitable, and sustainable catalysts in industrial processes, addressing the fact that even small changes in the ligand periphery of an active organometallic molecule can dramatically alter yields, product uniformity, selectivity, and turnover numbers. As a consequence, the synthesis and optimization of new ligands at c...

In the title binuclear centrosymmetric complex, [Cu(2)I(2)(C(8)H(6)N(4))(C(18)H(15)P)(2)]·2C(3)H(7)NO, the bis-bidentate 2,2'-bipyrimidine ligand bridges two copper(I) ions, each additionally bound to an iodide anion and a triphenyl-phosphane ligand in a distorted tetra-hedral N(2)IP geometry. The complex mol-ecules pack in columns parallel to [100] generating cavities occupied by dimethyl-form...

The title compound, [Pd(SC6H4F-p)Cl(PPh3)2]·0.5CH3OH, features a Pd(II) complex with two tri-phenyl-phosphane (PPh3) ligands arranged in a trans conformation, with one chloride and one 4-fluoro-benzene-thiol-ate ligand completing the coordination sphere, giving rise to a slightly distorted square-planar geometry of the Pd(II) ion. The methanol solvent mol-ecule is disordered about an inversion ...

In the title compound, [Ru(C(28)H(22)N(2)P)Cl(CO)(2)]·CH(2)Cl(2), the Ru(II) atom exhibits a distorted octa-hedral coordination geometry. The N-phenyl group of the ligand has undergone orthometalation; as a result, the tridentate phosphane-functionalized N-heterocyclic carbene ligand is coordinating in a meridional fashion. This complex is of inter-est with respect to transfer hydrogenation cat...

In the mononuclear title complex, [CuI(C(6)H(8)N(2)S)(C(18)H(15)P)(2)], the Cu(I) ion is in a slightly distorted tetra-hedral coordination geometry formed by two P atoms from two triphenyl-phosphane ligands, one S atom from a 4,6-dimethyl-pyrimidine-2(1H)-thione ligand and one iodide ion. There is an intra-molecular N-H⋯I hydrogen bond. In the crystal, π-π stacking inter-actions [centroid-centr...

In tetracoordinate cobalt(I) halide compounds CoX(Ph2P OH)(PMe3)2 (X = Cl, Br) o-phosphanylphenols Ph2P OH are coordinated as phosphane ligands. In the presence of base chelating anions Ph2P O give rise to pentacoordinate complexes Co(Ph2 P O)(PMe3)3. Molecular structures are presented for both types of compounds. The five-membered chelate ring in Co(Ph2P O)(PMe3)3 is resistant to protonation, ...

In the title solvate, [CuCl(C2H3N3S)(C18H15P)2]·CH3CN, the Cu(I) ion is bonded to two triphenyl-phosphane ligands, one 1H-1,2,4-triazole-5(4H)-thione ligand via its S atom and one chloride ion in a distorted CuP2SCl tetra-hedron. An intra-molecular N-H⋯Cl hydrogen bond, which closes an S(6) ring, helps to establish the conformation of the complex. In the crystal, N-H⋯Cl hydrogen bonds and C-H⋯π...

In the title compound, [RuCl(2)(C(6)H(6))(C(19)H(17)P)], the Ru(II) atom has a distorted pseudo-octa-hedral coordination environment with the metrical parameters around the metallic core as Ru-centroid(η(6)-benzene) = 1.6894 (11) Å, Ru-P = 2.3466 (6), Ru-Cl(avg.) = 2.4127 (7) Å; Cl-Ru-Cl = 88.07 (2) and Cl-Ru-P = 82.77 (2), 87.65 (2)°. The effective cone angle for the benzyl-diphenyl-phosphane ...
