trigonal planar. Please take note that it is a special case for boron trihydride because the octet configuration need not be achieved for Boron. As you can see, Boron atom has originally 3 valence electrons, not it has 6. It is short of two but it doesnt matter.

Bromine is single bonded to the three Iodines with two lone pairs. It has an expanded octet (which is fine because it is above period three). Its electronic geometry is trigonal bipyramidal and it has a T-shaped molecular geometry with bond angles of 90 degrees.
