Abstract

The complex [Mo(acac)(H2O)(η7-C7H7)]BF4 reacts with anionic nucleophiles to form neutral seventeen-electron paramagnetic compounds [Mp(acac)X(η7-C7H7)] (X = Cl, Br, I or NCS). Crystals of the thiocyanic derivative are monoclinic, space group P21/a with a = 12.762(2), b = 12.634(4) and c = 8.813(3) Å, β = 100.70(2)°; 2788 data ≥ 1.0σ have been employed to solve and refine the structure to a conventional R = 0.069. The molecule is almost identical with that of the cation [Mo(acac)(H2O)(η7-C7H7)]+ with a non-linear N-bonded thiocyanate function replacing the water molecule at MoN 2.122(10) Å.
