Tris(4-formylphenyl)phosphane oxide tetrahydrofuran hemisolvate
The title compound, C21H15O4P·0.5C4H8O, contains an ordered phosphane oxide in a general position and a tetra-hydro-furan solvent mol-ecule disordered about a twofold axis. All three aldehyde substituents are nearly coplanar with their attached benzene rings, with C-C-C-O torsion angles in the range 1.64 (17)-4.24 (19)°. All three have different conformations with respect to the P=O group, one ...
متن کامل(Tetrahydrofuran)potassium mer-trans-tris(carbazolyl)dichloro(tetrahydrofuran)zirconate.
In the title compound, [K(C(4)H(8)O)][ZrCl(2)(C(12)H(8)N)(3)(C(4)H(8)O)], the Zr atom is pseudo-octahedral, with two Cl ligands in trans positions. There is extensive interaction between the potassium cation and two of the aromatic carbazolyl ligands in eta(6) [C.K = 3.167 (3)-3.331 (3) A] and eta(2) [C.K = 3.147 (3)-3.268 (2) A] fashions.
متن کاملOxybis(dimesitylborane) dichloromethane hemisolvate
The title compound, C(36)H(44)B(2)O·0.5CH(2)Cl(2), contains an almost linear O-B-O linkage [177.23 (15)°] and approximately orthogonal [interplanar angles 89.49 (5) and 80.77 (4)°] trigonal planar B centers, consistent with the previously reported non-solvated structure [Cardinet al. (1983). J. Chem. Res. (S), p. 93]. Inter-molecular C-H⋯π inter-actions exist between mesityl groups, with a C-H⋯...
متن کاملKoetjapic acid chloroform hemisolvate
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 rota...
متن کاملBupropion hydrobromide propanol hemisolvate
The title compound {systematic name: N-[1-(3-chloro-phen-yl)-1-oxopropan-2-yl]-tert-butanaminium bromide propanol hemisolvate}, C(13)H(19)ClNO(+)·Br(-)·0.5C(3)H(8)O, crystallizes with two independent bupropion hydro-bromide ion pairs and a solvent 1-propanol mol-ecule in the asymmetric unit. In both mol-ecules, the expected proton transfer from HBr to the amino group of the bupropion mol-ecule ...
