Bis(2,4-dimeth-oxy-phen-yl)(phen-yl)phosphine selenide.

ABSTRACT: In the title mol-ecule, C(22)H(23)O(4)PSe, the P atom has a distorted tetra-hedral environment formed by the selenide atom [P=Se = 2.1219?(5)?Å] and three aryl rings. The orientations of the meth-oxy groups in the two 2,4-dimeth-oxy-phenyl ligands are distinct, as seen from the torsion angles: C-C-O-C = 14.7?(3) and 175.97?(17)° in one ligand, and -9.1?(2) and 5.1?(3)° in the other. In the crystal, weak inter-molecular C-H?Se inter-actions link the mol-ecules into zigzag chains propagated in [010].

In the title mol-ecule, C(22)H(23)O(4)PSe, the P atom has a distorted tetra-hedral environment formed by the selenide atom [P=Se = 2.1219 (5) Å] and three aryl rings. The orientations of the meth-oxy groups in the two 2,4-dimeth-oxy-phenyl ligands are distinct, as seen from the torsion angles: C-C-O-C = 14.7 (3) and 175.97 (17)° in one ligand, and -9.1 (2) and 5.1 (3)° in the other. In the crystal, weak inter-molecular C-H⋯Se inter-actions link the mol-ecules into zigzag chains propagated in [01 ...[more]

2,7-Dimeth-oxy-1,8-bis-(4-phen-oxy-benzo-yl)naphthalene.

Project description:In the title mol-ecule {systematic name: [2,7-dimethoxy-8-(4-phenoxybenzoyl)naphthalen-1-yl](4-phenoxyphenyl)methan-one}, C(38)H(28)O(6), the 4-phen-oxy-benzoyl units adopt a syn orientation with respect to the naphthalene ring system. The inter-nal benzene rings, A and B, make dihedral angles of 86.72?(5) and 79.22?(5)° with the naphthalene ring system. The two terminal benzene rings, C and D, of the 4-phen-oxy-benzoyl groups are twisted with respect to benzene rings A and B, with dihedral angles of A/C = 62.72?(8) and B/D = 87.61?(6)°. In the crystal, H atoms in the naphthalene system make two types of inter-molecular C-H?O inter-actions with the carbonyl O atom and the phenyl etheral O atom of neighbouring mol-ecules. Mol-ecules are further linked by C-H?? inter-actions involving a H atom of terminal benzene ring D and the ?-system of the inter-nal benzene ring A, forming dimers centered about an inversion center.

4,4'-Bis[2-(3,5-dimeth-oxy-phen-yl)ethen-yl]biphen-yl.

Project description:The title compound, C(32)H(30)O(4), crystallizes with three different conformers of the same mol-ecule in the asymmetric unit, which explains the unusually large unit cell volume. The supra-molecular structure is based on inter-actions involving the meth-oxy groups [C⋯O contacts between 3.090 (2) and 3.204 (2) Å, and C-H⋯O contacts between (normalized) 2.40 and 2.71 Å], π-π stacking of the electron-rich meth-oxy-substituted rings [centroid-centroid distances of 3.6454 (9)-3.738 (1) Å] and C-H⋯π contacts (normalized, 2.62-2.97Å).

[2,6-Bis(diphenyl-phosphino-oxy)phen-yl]bis-(trimethyl-phosphine)cobalt(I).

Project description:The title compound, [Co(C(30)H(23)O(2)P(2))(C(3)H(9)P)(2)], was synthesized by the addition of a Co(PMe(3))(4) solution to (PPh(2)O)(2)C(6)H(4).

The Co-C distance is 1.961?(2)?Å and the C-Co-P angle is 171.96?(6)°.
