Abstract
Gadolinium and terbium halides with halogen-to-metal ratios X/M < 2 contain distorted octahedral M6 units with a differing degree of condensation. With M2X3 being the only exception, additional non-metal atoms (hydrogen, carbon, silicon, nitrogen) occupy the cavities of the M6 units. The electrical behavior ranges from insulating to metallic. Temperature dependent metal-to-semiconductor transitions are observed for several compounds. The majority of the investigated materials exhibits antiferromagnetic ordering with Néel temperatures below 50 K.
