Bis(4-nitrophenyl) selenide
In the title compound, C12H8N2O4Se, the Se atom is situated on a twofold rotational axis, so the asymmetric unit contains one half-mol-ecule. In the mol-ecule, the C-Se-C angle is 99.48 (13)°, the two benzene rings are inclined to each other at an angle of 63.8 (1)° and the nitro group is twisted by 15.9 (1)° from the attached benzene ring. In the crystal, mol-ecules are held together through w...

In the title compound, C(16)H(14)O(2)Se, the dihedral angle between the benzene rings is 87.08 (11)°. In the crystal, mol-ecules are linked into layers parallel to the bc plane by inter-molecular C-H⋯O hydrogen bonds.
متن کامل(4-Ethenylphenyl)diphenylphosphine selenide
In the title mol-ecule, C(10)H(17)PSe, the P atom has a distorted tetra-hedral environment resulting in an effective cone angle of 165°. The benzene ring makes dihedral angles of 70.04 (8) and 77.28 (8)° with the phenyl rings, while the dihedral angle between the phenyl rings is 62.95 (8)°. In the crystal, mol-ecules are linked by C-H⋯π inter-actions.
متن کاملTris(4-methylphenyl)phosphine selenide
In the title mol-ecule, C(21)H(21)PSe or PSe(C(7)H(7))(3), the P atom has a distorted PSeC(3) tetra-hedral environment, formed by the Se atom [P=Se = 2.1119 (5) Å] and three aryl rings. Two short intra-molecular C-H⋯Se contacts occur. In the crystal, weak inter-molecular C-H⋯Se inter-actions link the mol-ecules into zigzag double chains propagating in [100]. The previous report of this structur...
متن کاملDicyclohexyl(4-isopropylphenyl)phosphane selenide
In the title compund, C(21)H(33)PSe, the Se=P bond is part of a distorted tetra-hedral environment on the P atom. Both cyclo-hexyl groups adopt chair conformations. A cone angle of 170° was calculated using an adaptation of the Tolman model. Inter-molecular C-H⋯Se and C-H⋯Cg contacts are observed (Cg is the centroid of the benzene ring).
