(1,2-Dicarba-closo-dodeca-boran-yl)trimethyl-methanaminium iodide.

ABSTRACT: The title compound, [1-(CH(3))(3)NCH(2)-1,2-C(2)B(10)H(11)](+)·I(-) or C(6)H(22)B(10)N(+)·I(-), was obtained by the reaction of (1,2-dicarba-closo-dodeca-boran-yl)dimethyl-methanamine with methyl iodide. The asymmetric unit contains two iodide anions and two (o-carboran-yl)tetra-methyl-ammonium cations. The bond lengths and angles in the carborane cage are within normal ranges, but the N-C(methyl-ene)-C(cage) angle is very large [120.2?(2)°] because of repulsion between the carborane and tetra-methyl-ammonium units. In the crystal, ions are linked through C-H?I hydrogen bonds.

Di-?-thio-cyanato-bis-{[1,2-bis-(diiso-propyl-phosphan-yl)-1,2-dicarba-closo-dodeca-borane]silver(I)}.

Project description:The title compound, [Ag(2)(NCS)(2)(C(14)H(38)B(10)P(2))(2)], was synthesized by the reaction of 1,2-bis-(diiso-propyl-phos-phan-yl)-1,2-dicarba-closo-dodeca-borane with AgSCN. The diisopropyl-phosphanyl-closo-carborane ligand is coordinated in a bidentate manner to the Ag(I) atom through the two P atoms. The coordination of the Ag(I) atom is distorted tetra-hedral, in which two vertices are formed by the P atoms of the chelating diphosphine ligand, and the other two are occupied by the S and N atoms of the two bridging thio-cyanate anions, leading to a centrosymmetric binuclear complex. The distance between the two C atoms in the carborane skeleton is 1.851?(6)?Å.

Project description:In the title complex, [HgCl(2)(C(14)H(38)B(10)P(2))], the Hg(II) atom is in a distorted HgCl(2)P(2) tetra-hedral coordination environment. The chelation of the Hg atom by two P atoms and two C atoms from the carborane skeleton results in a nearly planar five-membered ring.

Definitive crystal structure of 1,1'-bis-[1,2-dicarba-closo-dodeca-borane(11)].

Project description:In the title compound, C4H22B20, the two {1,2-closo-C2B10H11} cages are linked across a centre of inversion with a C-C distance of 1.5339?(11)?Å. By careful analysis of the structure, it is established that the non-linking cage C atom is equally disordered over cage vertices 2 and 3.

9-Ethynyl-1,2-dimethyl-1,2-dicarba-closo-dodeca-borane (1,2-Me(2)-9-HC C-closo-1,2-C(2)B(10)H(9)).

Project description:The asymmetric unit of the title compound, C(6)H(16)B(10), contains one mol-ecule that is close to possessing a non-crystallographic plane of mirror symmetry in the space group Pna2(1). The orientation of the mol-ecules in the ortho-rhom-bic cell shows that the structure can not be described in the space group Pnma, which has the same systematic absence conditions. The long inner-cluster C-C distance of 1.510?(5)?Å is typical for {1,2-Me(2)-closo-1,2-C(2)B(10)} derivatives.

Crystal structure of 1,1'-bis[1,7-dicarba-closo-dodeca-borane(11)].

Project description:In the title compound, C4H22B20, the two {1,7-closo-C2B10H11} cages are linked across a centre of inversion, with C-C = 1.5401?(16)?Å. The position of the second non-linking cage C atom was established unambiguously by geometric and crystallographic methods and there is no evidence of C/B disorder.

Bis(μ-nitrato-κ(2) O:O)bis-{[1,2-bis-(diiso-propyl-phosphan-yl)-1,2-dicarba-closo-dodeca-borane-κ(2) P,P']silver(I)} di-chloro-methane disolvate.

Project description:The title compound, [Ag2(NO3)2(C14H38B10P2)2]·2CH2Cl2, was synthesized by the reaction of 1,2-bis-(diiso-propyl-phosphan-yl)-1,2-dicarba-closo-dodeca-borane with AgNO3. The resulting dinuclear molecule has crystallographically imposed inversion symmetry. The diiso-propyl-phosphanyl-closo-carborane ligand is coordin-ated in a bidentate manner to the Ag(I) atom through the two P atoms. The distorted tetra-hedral coordination of the metal is completed by two O atoms of two bridging nitrate anions. The separation between the two Ag(I) atoms is 3.8913 (5) Å. C-H⋯O hydrogen bonds are observed involving the dichloromethane solvent molecule and the nitrate anion.

An ortho-rhom-bic polymorph of 1-[(ferrocen-yl)(hydr-oxy)meth-yl]-1,2-dicarba-closo-dodecaborane.

Project description:An ortho-rhom-bic polymorph of the title compound, [Fe(C(5)H(5))(C(8)H(17)B(10)O)] or C(13)H(22)B(10)FeO, is described here in addition to the known monoclinic polymorph [Crundwell et al. (1999 ?). Acta Cryst.C55, IUC9900087]. The asymmetric unit contains four independent mol-ecules with C(cage)-C(cage) distances of 1.636?(16)-1.700?(16)?Å, and with the methyl-hydr-oxy groups disordered over two positions in each mol-ecule [occupancy ratios 0.80?(2):0.20?(2), 0.59?(3):0.41?(3), 0.60?(2):0.40?(2) and 0.793?(17):0.207?(17)].

[1,2-Bis(diphenyl-phosphino)-1,2-dicarba-closo-dodeca-borane-κP,P'][7,8-bis-(di-phenyl-phosphino)-7,8-dicarba-nido-undeca-borato-κP,P']gold(I)-dichloro-methane-water (2/1/1).

Project description:The title compound, [Au(C(26)H(30)B(10)P(2))(C(26)H(30)B(9)P(2))]·0.5CH(2)Cl(2)·0.5H(2)O, contains two independent complex mol-ecules in the asymmetric unit. The gold(I) centres display a distorted tetra-hedral geometry. The complex is stablized through weak intra-molecular π-π stacking (Cg⋯Cg = 4.17 Å) and edge-to-face inter-actions (H⋯Cg = 3.21 Å). Adjacent mol-ecules inter-act through C-H⋯π (H⋯Cg = 2.88 Å) and B-H⋯π (H⋯Cg = 3.15 Å) contacts, forming a three-dimensional network, with solvent mol-ecules occupying the cavities. One of the phenyl groups was disordered over two sites with occupancy factors of 0.65 and 0.35.

[1,2-Bis(di-cyclo-hexyl-phosphan-yl)-1,2-dicarba-closo-dodeca-borane-2κ(2) P,P']di-μ-chlorido-1:2κ(4) Cl:Cl-di-chlorido-1κ(2) Cl-dimercury(II).

Project description:The title compound, [Hg2Cl4(C26H54B10P2)], was synthesized by the reaction of 1,2-bis-(di-cyclo-hexyl-phosphan-yl)-1,2-dicarba-closo-dodeca-borane with HgCl2. Both Hg(II) atoms show a distorted tetra-hedral coordination geometry, provided by the two bridging chloride anions and the P atoms of the diphosphanyl ligand for one metal atom, and by two bridging and two terminal chloride anions for the other. The five-membered HgP2C2 chelate ring assumes an envelope conformation, with the Hg(II) atom displaced by 0.1650 (5) Å from the mean plane of the other four atoms (r.m.s. deviation = 0.002 Å). In the crystal, B-H⋯Cl interactions link the molecules, forming a supramolecular chain along the a-axis direction.
