Dihydronium hexakis[bromido/chlorido(0.75/0.25)]dicadmate(II)-triphenylphosphine oxide (1/6)

K. M. Lo and S. W. Ng

Abstract: In the salt, (H₃O)₂[Cd₂Br_4.5Cl_1.5]·6C₁₈H₁₅OP, the hydronium cation forms short O-HO hydrogen bonds to the O atoms of the triphenylphosphine oxide units. The centrosymmetric dinuclear anion has two halide atoms functioning in a bridging mode, which confers tetrahedral coordination to the Cd atom. The three independent halide atoms are each a mixture of bromide and chloride; the occupancies of the Br atoms are 0.6434 (11), 0.7468 (11) and 0.8598 (11).
