Trans-Iodido(pyrazinyl-?C(2))bis-(triphenyl-phosphane-?P)palladium(II).

ABSTRACT: There are two independent mol-ecules with similar configurations in the asymmetric unit of the title complex, [Pd(C(4)H(3)N(2))I(C(18)H(15)P)(2)]. In each mol-ecule, the geometry around the Pd atom is distorted square-planar, with the Pd atom displaced by 0.0549?(12) and 0.0734?(13)?Å from the least-squares plane of the I-P-P-C atoms. The PPh(3) ligands are in trans positions, with P-Pd-P angles of 173.12?(4) and 170.29?(4)°, while the pyrazinyl ligands and I atoms, also trans to each other, form C-Pd-I angles of 179.38?(12) and 178.44?(12)°. In the crystal, C-H?? inter-actions occur, resulting in a three-dimensional supramolecular architecture.
