Tetra-bromidobis(dicyclo-hexyl-phosphane-?P)digallium(Ga-Ga).

ABSTRACT: The title compound, a Ga(II) dimer, [Ga(2)Br(4)(C(12)H(23)P)(2)], was synthesized by reaction of GaBr(THF)(n) (THF is tetra-hydro-furan) with dicyclo-hexyl-phosphine in toluene. At 150?K the crystallographically centrosymmetric molecule exhibits disorder in which one of the two independent cyclo-hexyl groups is modelled over two sites in a 62?(1):38?(1) ratio. In d(6)-benzene solution, the compound exhibits virtual C(2h) symmetry as determined by (1)H NMR. The coordination environment of the Ga(II) atom is distorted tetrahedral.

(?(6)-Benzene)-dichlorido(dicyclo-hexyl-phenyl-phosphane)ruthenium(II) benzene sesquisolvate.

Project description:The asymmetric unit of the title compound, [RuCl2(C6H6)(C18H27P)]·1.5C6H6, contains one mol-ecule of the Ru(II) complex and one and a half solvent molecules as one of these is located about a centre of inversion. The Ru(II) atom has a classical three-legged piano-stool environment being coordinated by an ?(6)-benzene ligand [Ru-centroid = 1.6964?(6)?Å], two chloride ligands with an average Ru-Cl bond length of 2.4138?(3)?Å and a dicyclo-hexyl-phenyl-phosphane ligand [Ru-P = 2.3786?(3)?Å]. The effective cone angle for the phosphane was calculated to be 158°. In the crystal, weak C-H?Cl hydrogen bonds link the Ru(II) complexes into centrosymmetric dimers. The crystal packing exhibits intra- and inter-molecular C-H?? inter-actions resulting in a zigzag pattern in the [101] direction.

Bis[dicyclo-hexyl-(phenyl)-phosphane-κP]silver(I) perchlorate dichloro-methane monosolvate.

Project description:In the title compound, [Ag{P(C(6)H(11))(2)(C(6)H(5))}(2)]ClO(4)·CH(2)Cl(2), the Ag(I) atom in the mononuclear complex cation is coordinated by two P atoms of the phosphane ligands [Ag-P = 2.3993 (4) and 2.4011 (4) Å; P-Ag-P = 177.473 (18)°] and the perchlorate anion acts as the counter-anion. There is an Ag⋯O(perchlorate) inter-action of 2.873 (2) Å, which contributes to the slightly non-linear bond angle about the Ag(I) atom. Weak inter-molecular C-H⋯O hydrogen-bonding inter-actions involving phenyl, cyclo-hexyl and dichloro-methane H-atom donors and perchlorate O-atom acceptors contribute to the stabilization of the crystal structure.

Chlorido{[2-(dicyclo-hexyl-phosphano-yl)eth-yl]bis-[2-(dicyclo-hexyl-phosphan-yl)eth-yl]phosphane}platinum(II) chloride dichloro-methane hemisolvate tetra-hydrate.

Project description:The title compound, [PtCl(C(42)H(78)OP(4))]Cl·0.5CH(2)Cl(2)·4H(2)O, crystallizes as a contact ion-pair with two close inter-molecular C-H?Cl(-) contacts between CH acidic ?H atoms of the phosphane ligand and the chloride anion. A chloride ligand together with three coordinating P ligand atoms create a slightly distorted square-planar coordination environment around the Pt(II) center. An inter-molecular water O-H?Cl(-) and water O-H?OP hydrogen-bond network completes the coordination around the anion. In addition, a disordered CH(2)Cl(2) solvent mol-ecule cocrystallized within a hydro-phobic cavity spanned by the dicyclo-hexyl-phosphane ligands.

(?(6)-Benzene)-dichlorido-(chloro-dicyclo-hexyl-phosphane-?P)ruthenium(II) chloro-form monosolvate.

Project description:The title compound, [RuCl2(?(6)-C6H6)(C12H22ClP)]·CHCl3, was prepared by reaction of [RuCl2(?(6)-C6H6)]2 with chloro-dicyclo-hexyl-phosphane in CHCl3 at 323?K under argon. The Ru(II) atom is surrounded by one arene ligand, two Cl atoms and a phosphane ligand in a piano-stool geometry. The phosphane ligand is linked by the P atom, with an Ru-P bond length of 2.3247?(4)?Å. Both cyclo-hexyl rings at the P atom adopt a chair conformation. In the crystal, the Ru(II) complex mol-ecule and the chloro-form solvent mol-ecule are linked by a bifurcated C-H?(Cl,Cl) hydrogen bond. Intra-molecular C-H?Cl hydrogen bonds are also observed.

Project description:The asymmetric unit of the title salt, C(12)H(24)N(+)·C(7)H(3)N(2)O(6) (-), contains two cations and two anions. In the crystal, the cations and anions are connected by N-H⋯O hydrogen bonds, forming a 12-membered ring with an R(4) (4)(12) graph-set motif. The center of this 12-membered ring coincides with an inversion centre. π-π stacking is observed between parallel benzene rings [centroid-centriod distance = 3.771 (2) Å].

N,N-Dicyclo-hexyl-4-nitro-benzamide.

Project description:The title compound, C(19)H(26)N(2)O(3), crystallizes with two independent mol-ecules in the asymmetric unit which differ in the twist of the phenyl rings with respect to the plane of the amide group [the C-C-C-O torsion angles are 121.5?(3) and -119.6?(3)° in the two mol-ecules. Both cyclo-hexane rings adopt chair conformations. In the crystal, weak C-H?O inter-actions occur. The crystal studied was a non-merohedral twin with a minor component of 4.8?(1)%.

Dicyclo-hexyl-ammonium hydrogen phenyl-phospho-nate.

Project description:In the title salt, [(C(6)H(11))(2)NH(2)](+)·[C(6)H(5)PO(2)(OH)](-), the anion is monodeprotonated and acts as both a hydrogen-bond donor and acceptor. The anions are linked by pairs of O-H?O inter-actions, forming inversion dimers with R(2) (2)(8) ring motifs. These dimers are bridged by two dicyclo-hexyl-aminium cations via pairs of N-H?O hydrogen bonds, giving R(4) (4)(12) ring motifs, forming chains propagating along [010]. The chains are bridged by C-H?O inter-actions, forming a two-dimensional network lying parallel to (101).
