Tris(naphthalen-1-yl)phosphane chloro-form hemisolvate.

ABSTRACT: The title compound, P(C10H7)3·0.5CHCl3, was isolated after the unsuccessful reaction of KSeCN and tris-(naphthalen-1-yl)phosphane. The solvent mol-ecule is disordered about an inversion center. The effective cone angle of the phosphine is 203°. In the crystal, weak C-H?Cl and C-H?? inter-actions are observed.

(?(6)-Benzene)(carbonato-?(2) O,O')[di-cyclohex-yl(naphthalen-1-ylmeth-yl)phosphane-?P]ruthenium(II) chloro-form tris-olvate.

Project description:The title compound, [Ru(CO3)(?(6)-C6H6){(C6H11)2P(CH2C10H7)}]·3CHCl3, was synthesized by carbonation of [RuCl2(?(6)-C6H6){(C6H11)2P(CH2C10H7)}] with NaHCO3 in methanol at room temperature. The Ru(II) atom is surrounded by a benzene ligand, a chelating carbonate group and a phosphane ligand in a piano-stool configuration. The crystal packing is consolidated by C-H?O and C-H?Cl hydrogen-bonding inter-actions between adjacent metal complexes and between the complexes and the solvent mol-ecules. The asymmetric unit contains one metal complex and three chloro-form solvent mol-ecules of which only one was modelled. The estimated diffraction contributions of the other two strongly disordered chloro-form solvent mol-ecules were substracted from the observed diffraction data using the SQUEEZE procedure in PLATON [Spek (2009 ?). Acta Cryst. D65, 148-155].

Koetjapic acid chloro-form hemisolvate.

Project description:The asymmetric unit of the title compound, C(30)H(46)O(4)·0.5CHCl(3), consists of one koetjapic acid [systematic name: (3R,4aR,4bS,7S,8S,10bS,12aS)-7-(2-carboxy-ethyl)-3,4b,7,10b,12a-penta-methyl-8-(prop-1-en-2-yl)-1,2,3,4,4a,4b,5,6,7,8,9,10,10b,11,12,12a-hexa-deca-hydro-chrysene-3-carboxylic acid] mol-ecule and one half-mol-ecule of chloro-form solvent, which is disordered about a twofold rotation axis. The symmetry-independent component is further disordered over two sites, with occupancies of 0.30 and 0.20. The koetjapic acid contains a fused four-ring system, A/B/C/D. The A/B, B/C and C/D junctions adopt E/trans/cis configurations, respectively. The conformation of ring A is inter-mediate between envelope and half-chair and ring B adopts an envelope conformation whereas rings C and D adopt chair conformations. A weak intra-molecular C-H?O hydrogen bond is observed. The koetjapic acid mol-ecules are linked into dimers by two pairs of inter-molecular O-H?O hydrogen bonds. The dimers are stacked along the c axis.
