rac-cis-Dicarbonyl-chlorido{1-[2-(diphenyl-phosphanyl-?P)benz-yl]-3-(phenyl-?C(1))imidazol-2-yl-idene-?C(2)}ruthenium(II) dichloro-methane monosolvate.

Project description: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 catalysis and also provides an example of C-H activation behavior in late transition metal complexes. The dichloro-methane solvent mol-ecule is disordered over two sets of sites with an occupancy ratio of 0.873?(14):0.127?(14).

rac-{[2-(Diphenyl-thio-phosphan-yl)ferrocen-yl]meth-yl}trimethyl-ammonium iodide chloro-form monosolvate.

Project description:The title compound, [Fe(C5H5)(C21H24NPS)]I·CHCl3, is built up from a (ferrocenylmeth-yl)trimethyl-ammonium cation, a iodine anion and a chloro-form solvent mol-ecule, all residing in general positions. The N atom of the ammonium group is displaced by 1.182?(2)?Å from the plane of the substituted cyclo-penta-dienyl (Cp) ring towards the Fe atom, whereas the C atom attached to the same Cp ring is slightly below this plane by -0.128?(2)?Å. These deviations might result from weak agostic interactions between the two H atoms of the CH2 group and the Fe atom.

cis-[1,4-Bis(diphenyl-phosphan-yl)butane-?(2)P,P']dichlorido(cyclo-hexane-1,2-diamine-?(2)N,N')ruthenium(II) dichloro-methane monosolvate.

Project description:In the title compound, [RuCl(2)(C(6)H(14)N(2))(C(28)H(28)P(2))]·CH(2)Cl(2), the Ru(II) ion is coordinated in a slightly distorted octa-hedral environment, formed by two cis-oriented chloride ligands, two cis P atoms of a 1,4-bis-(diphenyl-phosphan-yl)butane ligand and two cis-chelating N atoms of a bidentate cyclo-hexane-1,2-diamine ligand. In the crystal, pairs of mol-ecules form inversion dimers via N-H?Cl hydrogen bonds. In addition, intra-molecular N-H?Cl and weak C-H?Cl, C-H?N, N-H?? and C-H?? hydrogen bonds are observed. One of the Cl atoms of the solvent mol-ecule is disordered over two sites with refined occupancies of 0.62?(1) and 0.38?(1).

rac-Dichlorido(1-{(diphenyl-phosphan-yl)[2-(diphenyl-phosphan-yl)phen-yl]meth-yl}ferrocene-?P,P')palladium(II) dimethyl sulfoxide disolvate.

Project description:The racemic title compound, [FePdCl(2)(C(5)H(5))(C(36)H(29)P(2))]·2(CH(3))(2)SO, features a Pd-chelating 1,3-diphosphine, which is substituted at a P-bearing asymmetric C atom by a ferrocenyl group. The Pd(II) atom is in a distorted quadratic coordination by two P and two Cl atoms with bond lengths of 2.2414?(3) and 2.2438?(3)?Å for Pd-P, and 2.3452?(3) and 2.3565?(3)?Å for Pd-Cl. The conformation of the Pd complex is controlled by an intra-molecular slipped ?-? stacking inter-action between a phenyl and a cyclo-penta-dienyl ring with corresponding C?C distances starting at 3.300?(2)?Å and the distance between ring centroids being 3.674?(2)?Å. The crystal structure is stabilized by C-H?Cl and C-H?O hydrogen bonds. The (CH(3))(2)SO solvent mol-ecules are arranged in layers parallel to (101) and are linked in pairs by C-H?O inter-actions. One (CH(3))(2)SO mol-ecule is orientationally disordered [occupancy ratio 0.8766?(17):0.1234?(17)] with sulfur in two positions at both sides of its C(2)O triangle.

cis,trans-Dicarbonyl-dichlorido[2-(2-pyrid-yl)-1,8-naphthyridine-?N,N]ruthenium(II).

Project description:The asymmetric unit of the title compound, [RuCl(2)(C(13)H(9)N(3))(CO)(2)], consists of four crystallographically independent Ru(II) complexes. Each Ru(II) atom is in a distorted octa-hedral environment coordinated by two carbonyl ligands, two Cl atoms and a chelating 2-(2-pyrid-yl)-1,8-naphthyridine (pynp) ligand. The carbonyl ligands are cis to each other, while the Cl atoms are trans. Relatively short inter-atomic distances (2.60-2.67?Å) between the uncoordinated N atom of pynp and the C atom of the carbonyl imply a donor-acceptor inter-action between the pynp and carbonyl ligands.

cis-Dichlorido[2-(3,5-dimethyl-1H-pyrazol-1-yl-?N(2))ethanamine-?N]palladium(II) dichloro-methane monosolvate.

Project description:In the title compound, [PdCl(2)(C(7)H(13)N(3))]·CH(2)Cl(2), the 2-(3,5-dimethyl-1H-pyrazol-1-yl)ethanamine ligand chelates the Pd(II) atom via two N atoms forming a six-membered ring resulting in a distorted square-planar metal coordination environment, highlighted by N-Pd-Cl angles of 172.63?(8) and 174.98?(9)°. In addition to N-H?Cl hydrogen bonds creating infinite chains along [001], several C-H?Cl inter-actions are observed in the crystal structure.

Dichlorido{N-[2-(diphenyl-phosphan-yl)benzyl-idene]isopropyl-amine-?N,P}palladium(II) dimethyl sulfoxide monosolvate.

Project description:In the title Pd(II) complex, [PdCl(2)(C(22)H(22)NP)]·(CH(3))(2)SO, the Pd(II) atom is coordinated in an NPCl(2) coordination sphere by the N(imino) and P(phosphane) atoms of the ligand and by two Cl(-) ions in a slightly distorted square-planar geometry [r.m.s. deviation = 0.081?(3)?Å, plane defined by the four atoms around the Pd atom]. The dimethyl sulfoxide solvent mol-ecules form centrosymmetric dimers due to an inter-molecular C-H?O inter-action. The crystal structure is further stabilized through two inter-molecular C-H?? inter-actions.

rac-2,2'-Bis(diphenyl-phosphan-yl)-1,1'-binaphth-yl: a racemic diphosphine ligand.

Project description:The asymmetric unit of the title compound, C(44)H(32)P(2), conventionally abbreviated BINAP, is one half of the complete chiral BINAP mol-ecule, which adopts a C2 crystallographic point-group symmetry with a twofold axis splitting the mol-ecule in two identical halves; a center of symmetry between mol-ecules further determines the racemic pairs. There are no obvious supra-molecular inter-actions between adjacent BINAP mol-ecules.

cis-Dichlorido-tetra-kis-(dimethyl sulfoxide-?O)chromium(III) chloride dimethyl sulfoxide monosolvate.

Project description:The structure of the title compound, [CrCl2(C2H6OS)4]Cl·C2H6OS, consists of a Cr(III) ion coordinated by four O atoms of dimethyl sulfoxide (DMSO) ligands and two chloride ions in cis positions, forming a distorted CrCl2O4 octa-hedron. An isolated Cl(-) counter-anion and a positionally disordered DMSO mol-ecule [occupancy ratio 0.654?(4):0.346?(4)] are also present. In the structure, the complex cations inter-act with the Cl(-) counter-anions and the DMSO solvent mol-ecules via weak C-H?Cl and C-H?O inter-actions, forming a three-dimensional network.

Project description:In the title compound, [AuCl(C(25)H(23)N(2)P)], the Au(I) atom is in a typical almost linear coordination environment defined by phosphane P and Cl atoms [bond angle = 175.48?(4)°]. Helical supra-molecular chains along the b axis and mediated by N-H?Cl hydrogen bonds feature in the crystal packing.
