Identify linear chemical species from icl2- and of2+ and if2+

Dear Student,
ICl_​2^- has sp³d hybridization having trigonal bipyramidal geometry with a linear structure.  The 2Cl^- are present on the axial plane while the lone pairs are present on the equatorial plane . Thereby the repulsion is minimum and structure is linear.

While  OF₂⁺ and IF₂⁺ have a bent structure due to repulsion between lone pair and bond pairs.
Regards!
