Bis[4-(dimethylamino)pyridinium] 3.75-bromido-0.25-chloridodiphenylplumbate(IV)

K. M. Lo and S. W. Ng

Abstract: The Pb^IV atom of the plumbate dianion in the title compound, (C₇H₁₁N)₂[Pb(Br_3.75Cl_0.25)(C₆H₅)₂], lies on a centre of inversion in a tetragonally compressed octahedral geometry. One of the attached Br atoms is disordered with respect to a Cl atom in a 7:1 ratio. The disordered halogen atom is an N-H(Br/Cl) hydrogen-bond acceptor for the cation.
