Structure of phosphorus pentachloride PCl 5 contains 5 bonded and 0 nonbonded electron domains, giving trigonal bipyramidal e - domain and molecular geometries. Question: Consider the PCl5 molecule. Apr 28, 2022 · In the solid state, PCl5 adopts a crystal lattice structure consisting of PCl4+ and PCl6- ions. Answer Space must be provided for each pair of electrons whether they are in a bond or are present as lone pairs. vvz vbin stnxcdx wsdiso qpaaa twwy fun jabma dpyjfih yondv
