Crystals of 9,9-(η2-2,2′-bipyridine)-2,7-bis(t-butyl)-dibenzoplatinol are monoclinic, space group P21/a; a 17.874, b 9.849, c 15.123 Å; α = γ = 90.00, β 109.51°; Z = 4; Dx 1.629, Dm 1.628 g cm−3, flotation method in CCl4/CHBr3; M = 615.7; Mo-Kα 0.71069 Å, graphite monochromator; F(000) = 1219.82; T 295 K; of the 4416 measured reflexions, 3513 were taken as observed; final R = 0.0528. Bipyridine and 4,4′-disubstituted biphenyl ligand are strongly distorted from the coplanar orientation and as a consequence the single molecule contains no symmetry element. In the unit cell both enantiomers of the chiral molecules are symmetrically oriented pairwise with respect to the axis of symmetry.
