[?-3,3'-Bis(tri-hydro-bor-yl)[3]ferroceno-phane]bis-(chlorido-zirconocene).

ABSTRACT: The title compound, [FeZr2(C5H5)4Cl2(C13H18B2)], is a heteronuclear complex that consists of a [3]ferrocenophane moiety substituted at each cyclo-penta-dienyl (Cp) ring by a BH3 group; the BH3 group is bonded via two H atoms to the Zr atom of the zirconocene chloride moiety in a bidentate fashion. The two Cp rings of the [3]ferrocenophane moiety are aligned at a dihedral angle of 8.9?(4)° arising from the strain of the propane-1,3-diyl bridge linking the two Cp rings. [One methyl-ene group is disordered over two positions with a site-occupation factor of 0.552?(18) for the major occupied site.] The dihedral angles between the Cp rings at the two Zr atoms are 50.0?(3) and 51.7?(3)°. The bonding Zr?H distances are in the range 1.89?(7)-2.14?(7)?Å. As the two Cp rings of the ferrocene unit are connected by an ansa bridge, the two Zr atoms approach each other at 6.485?(1)?Å. The crystal packing features C-H?Cl inter-actions.

Project description:In the title monomeric rare earth complex, [LiNd(C(19)H(40)N(3)Si(2))(2)Cl(2)(C(4)H(8)O)(2)], the [(Me(3)Si)(2)NC(NCy)(2)](2)Nd(+) (Me is methyl, Cy is cyclo-hex-yl) and Li(THF)(2) (+) units (THF is tetra-hydro-furan) are connected by two bridging Cl atoms. The Nd(3+) ion is coordinated by two guanidinate ligands and two Cl atoms, forming a distorted chelating octa-hedral geometry. The Li(+) ion is four-coordinated by two Cl atoms and two O atoms from THF mol-ecules in a distorted tetra-hedral geometry.

Chlorido[5-meth-oxy-1H-benzimidazole-2(3H)-thione-?S]bis-(tri-phenyl-phos-phane-?P)copper(I) methanol disolvate.

Project description:In the title complex, [CuCl(C8H8N2OS)(C18H15P)2]·2CH3OH, the Cu(I) ion is coordinated by one chloride anion, one S atom from the 5-meth-oxy-1H-benzimidazole-2(3H)-thione ligand and two P atoms from two tri-phenyl-phosphine ligands in a distorted tetra-hedral geometry. One of the N-bound H atoms is involved in an intra-molecular N-H?Cl hydrogen bond, while another one inter-acts with the solvent methanol mol-ecule via an N-H?O hydrogen bond. Inter-molecular O-H?Cl and O-H?O hydrogen bonds link two further complex mol-ecules and four solvent mol-ecules into a centrosymmetric structural unit. The short distance of 3.624?(4)?Å between the centroids of the five- and the six-membered rings of two benzimidazole fragments indicates the presence of ?-? inter-actions.

Di-chlorido-bis-[1-(2,4,6-tri-methyl-phen-yl)-1H-imidazole-?N (3)]copper(II).

Project description:In the title complex, [CuCl2(C12H14N2)2], the Cu(2+) cation is situated on an inversion centre and is coordinated by two N atoms from symmetry-related 1-mesityl-1H-imidazole ligands and by two chloride anions in a slightly distorted square-planar geometry. In the organic ligand, the dihedral angle between the benzene ring of the mesityl moiety and the imidazole ring is 76.99?(18)°. Weak intra-molecular C-H?Cl hydrogen-bonding inter-actions consolidate the mol-ecular conformation.

Tri-?-chlorido-bis-[(?-hexa-methyl-benzene)-ruthenium(II)] tetra-chlorido-ferrate(III).

Project description:The mol-ecular geometry of the complex cation in the title structure, [(?-Cl)(3){Ru(II)(?(6)-C(6)Me(6))}(2)][Fe(III)Cl(4)], compares very well with that reported earlier for the corresponding PF(6) (-) salt [Pandey et al. (1999 ?). J. Organomet. Chem.592, 278-282]. The [FeCl(4)](-) counter ion has a rather regular tetra-hedral geometry with Fe-Cl distances and Cl-Fe-Cl angles in the range 2.1891?(7)-2.2018?(8)?Å and 107.10?(3)-110.56?(3)°, respectively. There are no significant inter-molecular inter-actions in the crystal except for some weak C-H?Cl contacts, which in turn indicates that the crystal packing is determined predominantly by electrostatic inter-actions between the ionic constituents.

Bis(dihydrogen norfloxacinium) tri-?(2)-chlorido-bis-[trichloridobismuthate(III)] chloride dihydrate.

Project description:The title compound, {systematic name: (3-carb-oxy-1-ethyl-6-fluoro-7-piperazin-4-ium-1-yl-1H-quinolin-4-yl-idene)oxonium tri-?(2)-chlorido-bis-[trichloridobismuthate(III)] chloride dihydrate], (C(16)H(20)FN(3)O(3))(2)[Bi(2)Cl(9)]Cl·2H(2)O, is composed of [Bi(2)Cl(9)](3-) anions lying on crystallographic twofold rotation axes, Cl(-) anions also on twofold axes, C(16)H(20)FN(3)O(3) (2+) cations, and water mol-ecules. The Bi(III) coordination polyhedron is a distorted octa-hedron and two such octa-hedra share a triangular face to form the complex anion. There are three short terminal Bi-Cl bonds [2.5471?(6)-2.5781(5?Å] and three longer bridging bonds [2.8599?(5)-2.9984?(6)?Å] in each octa-hedron. Anions, cations and water mol-ecules are linked by hydrogen bonds to form a three-dimensional network. There are also ?-? stacking inter-actions between quinoline ring systems, with an inter-planar distance of 3.27?(1)?Å.

4-(3,3-Dimethyl-perhydro-1,3-oxa-zolo[3,4-a]pyridin-1-yl)-2,8-bis-(tri-fluoro-meth-yl)quinoline.

Project description:An L-shaped conformation is found in the title mol-ecule, C(20)H(20)F(6)N(2)O, the C-C-C-C torsion angle linking the two fused-ring systems being -92.80?(19)°. The oxazole ring adopts an envelope conformation [the N atom lies 0.579?(2)?Å out of the plane defined by the remaining atoms], and the piperidine ring has a chair conformation. Supra-molecular chains are found in the crystal structure that are sustained by C-H?? and ?-? [3.6089?(10)?Å] inter-actions.

Di-?-chlorido-bis-{[?-1,8-bis-(diisopropyl-phosphan-yl)-9,10-dihydro-9,10-ethano-anthracene-?P:P']-?-chlorido-?-methyl-idene-dipalladium(II)} tetra-hydro-furan penta-solvate.

Project description:The title compound, [Pd(4)(CH(2))(2)Cl(4)(C(28)H(40)P(2))(2)]·5C(4)H(8)O, possesses a tetra-nuclear palladium core with four bridging chlorido ligands and two bridging methyl-ene units, as well as two bridging anthracene-based bis-phosphine ligands. This tetra-nuclear complex can be considered as being composed of two ?-chlorido-bridged LPd(2) units. The structural motif of these LPd(2) units shows two doubly bridged palladium centers between the P atoms of the bis-phosphine ligand. One of these bridges is a ?-Cl atom, the other a ?-methyl-ene group. The coordination environment around each palladium center is essentially square planar. We ascribe the oxidation state +II to the palladium centers and do not assume Pd-Pd bonds [shortest distances 2.8110?(5) and 2.8109?(6)?Å]. Co-crystallized with the palladium complex we found five non-coordinating tetra-hydro-furan solvent mol-ecules, one of which is disordered over two positions in a 0.429?(9):0.571?(8) ratio.

Tri-methyl-phospho-nium trans-tetra-chlorido-bis-(tri-methyl-phosphane-?P)iridate(III).

Project description:The title compound, [HP(CH3)3][IrCl4{(H3C)3P}2], consists of a tri-methyl-phospho-nium cation and a tetra-chlorido-bis-(tri-methyl-phosphane)iridate(III) anion. The anion has an octa-hedral arrangement of ligands, with the tri-methyl-phosphane groups occupying trans positions. The Ir(III) atom sits on an inversion center with one P(CH3)3 ligand and two chloride ligands in the asymmetric unit. The tri-methyl-phospho-nium cation is disordered about a twofold rotation axis. The title compound is the first structurally characterized tetra-chlorido-bis-(phosphane)iridate complex.

?-(Acetic acid)-di-?-chlorido-bis[tri-phenyl-tellurium(IV)] monohydrate.

Project description:The asymmetric unit of the title compound, C38H34Cl2O2Te2·H2O, contains two independent Te(IV) cations, each coordinated by three phenyl ligands, two Cl(-) anions and one acetic acid mol-ecule in a distorted octa-hedral C3Cl2O geometry; the longer Te?Cl distances ranging from 3.2007?(11) to 3.4407?(11)?Å and the longer Te?O distances of 3.067?(3) and 3.113?(3)?Å indicate the weak bridge coordination. The Cl(-) anion and acetic acid mol-ecule bridge the two independent Te(IV) cations, forming the dimeric complex mol-ecule, in which the Te?Te separation is 3.7314?(4)?Å. In the crystal, the water molecules of crystallization link the Te(IV) complex mol-ecules into chains running along the b-axis direction via O-H?O and O-H?Cl hydrogen bonds.

Tri-?-chlorido-bis-[(?(5)-penta-methyl-cyclo-penta-dien-yl)rhodium(III)] hexa-fluorido-phosphate from synchrotron radiation.

Project description:In the title complex salt, [{(?(5)-C5Me5)Rh}2(?-Cl)3]PF6, the dinuclear, single-charged cation is formed by the cojoining of two classic (?(5)-C5Me5)RhCl3 'piano-stool' units by bridging of the three choride ligand 'legs'. The crystal structure shows several close H?F contacts between the hexa-fluorido-phosphate counter-ions and the C5Me5 ligands.
