Popis:	Bismuth compounds Ph3Bi[OC(O)R]2 (R = CH2C6H4F-3, C6H3F2-2,3, C6HF4-2,3,4,5) were synthesized by the reaction of triphenylbismuth with a carboxylic acid and tert-butyl hydroperoxide (1 : 2 : 1 mol.) in diethyl ether. Structural features of these compounds were determined by the single crystal X-ray analysis method. Bismuth atoms in triphenylbismuth dicarboxylates have distorted trigonal-bipyramidal coordination with oxygen atoms in axial positions. The presence of intramolecular contacts Bi···O(=C) [2.833(8)–3.136(9) A] causes an increase in one of CBiC bond angles to 151.07(15)°, 142.0(3)°, 138.53(14)°, respectively, due to a decrease in the other two angles.
