The bis(triphenylphosphine)silver complexes of (phenalenone) 6, (diphenylcyclopropenone) 7, (tropone) 8, bis(phenalenone) 9, bis(diphenylcyclopropenone) 10 and bis(tropone) 11 were prepared by treating bis(triphenylphosphine)silver tetrafluoroborate 5 with the respective basic ketones phenalenone 2, diphenylcyclopropenone 3 or tropone 4 in 1 or 2 equiv. amounts. The first crystal structure of diphenylcyclopropenone adduct (complex 10, (Ph3P)2(diphenylcyclopropenone)2Ag+BF-4) was determined confirming the silver to oxygen σ-bonds. The complex 10 crystallizes in the monoclinic space group P21/c, with a= 10.419(3)A, b = 25.291(7)A, c = 20.711(4)A, β = 91.916(4)°, Z = 4, V = 5454.6(24)A3, RF = 0.077, RW = 0.083 for 7114 reflections.
