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)).

ABSTRACT: 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.

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.

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.

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.

4-(Dimethyl-amino)phenyl ethynyl telluride.

Project description:The title compound, C(10)H(11)NTe, is the first organyl ethynyl telluride, R-Te-C C-H, to be structurally characterized. In the L-shaped mol-ecule, the aryl moiety, viz. Me(2)NC(6)H(4)Te, is almost perpendicular to the Te-C C-H fragment. The Te-Csp(2) bond [2.115 (3) Å] is significantly longer than the Te-Csp bond [2.041 (4) Å]. The Te-C C group is approximately linear [Te-C-C = 178.5 (4)° and C C = 1.161 (5) Å], while the coordination at the Te atom is angular [C-Te-C = 95.92 (14)°]. In the crystal structure, there are Csp-H⋯N hydrogen bonds which are perpendicular to the CNMe(2) group; the N atom displays some degree of pyramidalization. Centrosymmetrically related pairs of mol-ecules are linked by Te⋯π(ar-yl) inter-actions, with Te⋯Cg = 3.683 (4) Å and Csp-Te⋯Cg = 159.1 (2)° (Cg is the centroid of the benzene ring). These inter-actions lead to the formation of zigzag ribbons which run along c and are approximately parallel to (110).

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.

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.

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-Dicarba-closo-dodeca-boran-yl)trimethyl-methanaminium iodide.

Project description: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.

Crystal structures of dimethyl 5-iodo-iso-phthal-ate and dimethyl 5-ethynyl-iso-phthal-ate.

Project description:In dimethyl 5-iodo-isophthalate, C10H9IO4, (I), the planes through the methyl carboxyl-ate moieties are tilted with respect to the benzene ring, whereas the mol-ecular framework of dimethyl 5-ethynylisophthalate, C12H10O4, (II), is perfectly planar. The crystal structure of (I) is stabilized by a three-dimensional supra-molecular network comprising C-H?O=C hydrogen bonds, as well as I?O=C inter-actions. In the crystal of (II), the mol-ecules are connected via C-Hethyn-yl?O=C hydrogen bonds to infinite strands. Moreover, ?-? arene stacking inter-actions connect the mol-ecular chains into two-dimensional supra-molecular aggregates.
