Synthesis, and crystal and molecular structure of µ-dibromo-µ-tetraphenyl-diphosphane-bis[tricarbonylrhenium(I)], a molecule containing a new type of tetraphenyldiphosphane bridge
Abstract
No cleavage of the P–P bond occurs during the reaction of the tetrahydrofuran (thf) complex [Re2Br2(CO)6(thf)2] with P2Ph4 in toluene; an X-ray study shows that the resulting compound contains bridging tetraphenyldiphosphane in a unique type of bonding.
