Diphenyl[2-(2-pyridylaminomethyl)phenyl]phosphine oxide
نویسندگان
چکیده
The title compound, C(24)H(21)N(2)OP, was obtained by reacting 2-amino-pyridine and 2-(diphenyl-phosphin-yl)benzaldehyde in ethanol. It crystallizes with two crystallographically independent mol-ecules in the asymmetric unit. The amino-pyridine units and the benzene ring bonded to the phosphine oxide P atom form dihedral angles of 88.58 (7) and 82.47 (9)° in the two mol-ecules. The crystal structure displays strong N-H⋯O and weak C-H⋯O hydrogen bonds along the b axis and C-H⋯π aromatic intra- and inter-molecular inter-actions.

The title compounds, C36H28OP2S2, (1), and C36H28OP2Se2, (2), exhibit remarkably similar structures although they are not isomorphous. The whole mol-ecule of compound (2) is generated by twofold symmetry, with the ether O atom located on the twofold axis. Both compounds have intra-molecular π-π inter-actions between terminal phenyl rings with centroid-centroid distances of 3.6214 (16) and 3.802...

In the title compound, [PdBr(2)(C(19)H(17)P)(2)], the Pd(II) ion resides on a centre of symmetry and is coordinated by two Br anions [Pd-Br = 2.4266 (2) Å] and two P-donor ligands [Pd-P = 2.3462 (5) Å] in a slightly distorted square-planar geometry [P-Pd-Br = 93.528 (12)°]. Weak inter-molecular C-H⋯Br hydrogen bonds link mol-ecules into chains extended in [10].

At 120 K, the title compound, C(24)H(42)NO(2)P, crystallizes in a unit cell with a doubled a parameter compared with the room-temperature structure. There are four mol-ecules in the asymmetric unit, one of which shows extensive disorder in a 0.588 (3):0.412 (3) ratio. In the crystal, numerous C-H⋯O inter-actions link the mol-ecules.

The title deuterated tripodal phosphine, C(21)H(12)D(9)PS(3)·0.125CDCl(3), crystallizes as two independent mol-ecules, one of which lies on a general position and the other about a threefold rotation axis, and as a deuteriochloro-form solvate. The solvent mol-ecule is disordered about a site of symmetry 3, so that the ratio of phosphine to solvent is 8:1. The P atom adopts a pyramidal coordinat...

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(I) atom displays a trigonal-bipyramidal geometry with the two P atoms of the 'PCP' pincer ligand and the P atom of one of the trimethyl phosphine ligands forming the basal plane, whereas the metalated C atom and the P atom of the second phospine...
