Aquabis(triphenylphosphine-κP)copper(I) tetrafluoridoborate

In the title compound, [Cu(C18H15P)2(H2O)]BF4, the CuI atom is coordinated by two P atoms from triphenylphosphine ligands and one water molecule in a distorted trigonal geometry. In the BF4− anion, three F atoms are disordered over two sites around the B—F bond, the site-occupancy ratio being 0.67 (6):0.33 (6). The Cu...F distance of 2.602 (5) Å between the Cu atom and the ordered F atom may suggest a weak but genuine interaction. O—H...F and weak C—H...F hydrogen bonding is present in the crystal structure.
