Abstract: In the title molecule, [Bi(C6H5)3(C4H5O2)2], the BiV atom is in a distorted trigonal-bipyramidal environment with carboxylate O atoms in axial positions and phenyl C atoms in the equatorial plane. The Bi-O bond lengths are 2.283 (3) and 2.309 (2) Å, but as a result of additional long Bi...O interactions [2.787 (3) and 2.734 (3) Å], one of the C-Bi-C angles is 148.62 (13)°. In the crystal, weak C-H...O hydrogen bonds connect pairs of molecules into inversion dimers. These dimers are further connected by weak C-H...[pi] interactions into chains along [100] .
