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...
