metal-organic compounds
The coordination geometry at the Sn atom in the title compound, [Sn(C6H5)2(C9H6NO)2], is distorted cis-octahedral, in which the two phenyl ligands are cis to one another and trans to the N atoms of the oxinate ligands. This arrangement brings the oxinate O atoms into a trans relationship and is the geometry adopted most frequently by diorganotin(IV) oxinates. The OO vector in the molecule is almost parallel to the plane of every ligand.
organic compounds
In the title compound, C23H27NO4, a modified synthetic D-homo steroid, the cyclohexene ring adjacent to the aromatic ring adopts a half-chair conformation, while the cyclohexane ring has an ideal chair conformation and the heterocyclic ring has a sofa conformation. The plane of the allyl substituent lies almost perpendicular to the least-squares plane of the heterocyclic ring. The crystal structure contains a series of weak C—HO intermolecular interactions.
metal-organic compounds
The title compound, [Sn2(C6H5)5(C11H11NO3)Cl], is a dinuclear organotin adduct in which the two Sn atoms are bridged via the carboxylate O—C—O group of a 2-[(E)-1-(2-hydroxyaryl)alkylideneamino]acetate ligand. Each Sn atom has a distorted trigonal bipyramidal geometry, with the Ph3SnCl moiety being less distorted.
organic compounds
In the crystal structure of the title compound, C13H12O3S, the dihedral angle between the mean planes of the 4-tolyl and phenyl rings is 52.6 (1)°. There are weak C—HO hydrogen bonds, which generate rings of graph-set motifs R12(4) and R21(9). The supramolecular aggregation is completed by the presence of van der Waals short contacts and C—Hπ interactions.
metal-organic compounds
The title compound, [Sn(C4H9)3(C21H16N3O3)]n, is a one-dimensional polymer in which the two carboxylate O atoms of a single benzoate ligand bridge adjacent SnBu3 groups. The Sn atom has a slightly distorted trans-Bu3SnO2 trigonal–bipyramidal coordination geometry.
organic compounds
In the title compound, C22H29NO3, a modified synthetic D-homo steroid, the cyclohexene ring adjacent to the aromatic ring adopts a half-chair conformation, while the cyclohexane ring has an ideal chair conformation. The heterocyclic ring adopts a 14β-sofa conformation. The butyl substituent is nearly planar, this plane lying almost perpendicular to the least-squares plane of the heterocyclic ring. Intermolecular O—HO hydrogen bonds link the molecules into extended chains and the compound also exhibits some weak intermolecular C—HO interactions.
organic compounds
In the title compound, C23H31NO3, a modified synthetic D-homo steroid derivative, the cyclohexene ring adjacent to the aromatic ring adopts a half-chair conformation, while the cyclohexane ring has an ideal chair conformation. The heterocyclic ring adopts a 14α-sofa conformation. The butyl substituent is nearly planar, this plane lying almost perpendicular to the least-squares plane of the heterocyclic ring. The structure displays some weak intermolecular C—HO interactions.
organic compounds
In the title compound, C9H8N2O2S, the H atom of the thiol group has been transferred to the neighbouring N atom of the oxadiazole ring. Intermolecular N—HN hydrogen bonds exist between adjacent molecules.
