Catching Wyckoff’s Phantom: The Peculiar Crystal Structure of Orthorhombic Cs[ICl 2 ]

The crystal structure of the thus far elusive orthorhombic modification of Cs[ICl 2 ] ( Pnma , Z  = 4, a  = 1042.2(1) pm, b  = 647.35(5) pm, c  = 870.38(8) pm and V  = 587.21(9) Å 3 ) is reported. In contrast to the structure of the known trigonal modification ( R m ), the [ICl 2 ] − anion show...
