The PF3Br2 molecule has a trigonal bypiramidal geometry. The three F atoms surround the P atom in the same plane and each F-P-F bond has a bond agle of 120 degrees. There is one Br atom above and below the P atom so, the Br-P-Br bond angle is 180 degrees. Finally, the F-P-Br bond angle is 90 degrees.
