Mn. Gibbons et al., BIPHENYL-2,2'-DIYLPHENYLANTIMONY DIBROMIDE - A NEW SQUARE PYRAMIDAL ANTIMONY(V) COMPOUND, Journal of organometallic chemistry, 469(2), 1994, pp. 30000025-30000026
In contrast to the trigonal bipyramidal geometry of triphenylantimony
dibromide, the related biphenyl-2,2'-diylphenylantimony dibromide has
a distorted square pyramidal arrangement of ligands about antimony and
is dimeric in the solid state.
