The title compound, C(42)H(63)O(4)P, was isolated from the leaves of Vitex negundo. Two of the tert-butyl groups are disordered over two orientations with occupancy ratios of 0.57 (1):0.43 (1) and 0.67 (1):0.33 (1). Several intra-molecular C-H⋯O inter-actions are observed in the mol-ecular structure.
متن کاملTris(3-aminophenyl)phosphine oxide ethanol solvate
The title compound crystallized as an ethanol solvate, C(18)H(18)N(3)OP·C(2)H(6)O. It is the reduction product of tris-(3-nitro-phen-yl)phosphine oxide. In the crystal, there are inter-molecular N-H⋯O hydrogen bonds between neighbouring tris-(3-amino-phen-yl)phosphine oxide mol-ecules and O-H⋯O hydrogen bonds involving the ethanol solvent mol-ecule.

The rhenium(V) complex [(HCpz3)ReOCl2]+ ([1]+), the tris(pyrazolyl)methane analogue of the known tris(pyrazolyl)borate complex (HBpz3)ReOCl2 (2), has been prepared. The two complexes are strikingly similar, as are the phosphine oxide adducts [(HCpz3)ReCl2(OPPh3)]Cl ([3]Cl) and (HBpz3)ReCl2(OPPh3) (4), which have been characterized by X-ray crystallography. Comparison of the bimolecular reductio...

In the title compound, C(36)H(44)N(4)O(4)S, the dihedral angles between the central thio-phene ring and the pendent oxadiazole rings are 12.7 (2) and 13.7 (2)°, and the dihedral angles between the oxadiazole rings and their adjacent benzene rings are 6.1 (2) and 17.5 (2)°. An intra-molecular C-H⋯O inter-action may help to establish the conformation.
