(2,2′-Bi­pyrazine-κ2N1,N1′)[1,2-bis­(di­phenyl­phosphan­yl)methane-κP]tri­carbonyl­rhenium(I) tri­fluoro­methane­sulfonate monohydrate

The title compound, [Re(C8H6N4)(C25H22P2)(CO)3]CF3SO3·H2O, crystallizes with one [Re(C8N4H6){P(Ph)2CH2P(Ph)2}(CO)3]+ cation, where Ph is a phenyl group, one CF3SO3− anion and one water mol­ecule of hydration. The three C atoms of the facial oriented carbonyl groups, two N atoms from the bi­pyrazine ligand and one P atom from the (bis­)di­phenyl­phosphanyl­methane ligand define a distorted octa­hedral coordination environment about the central ReI atom. The Re—Ccarbon­yl bond length trans to the P atom is longer than the the two Re—Ccarbon­yl bond lengths in the plane with the bi­pyrazine ligand. Hydrogen-bonding inter­actions between the solvent water mol­ecule and the cation, as well as weak C—H⋯O inter­actions, consolidate a three-dimensional network structure.
