Abstract

The cross-linked chain cobalt oxychloride Ba5Co5ClO13 is reported. Single crystals were obtained by a flux method with BaCl2. A hexagonal unit cell (P63/mmc, a = 5.6980(8) Å and c = 24.469(5) Å) was found. The + 3 and + 4 valence cobalt ions were formally distributed into octahedral and tetrahedral sites coordinated by oxide ions. The compound was electrically insulating with a gap of 0.25 eV along the chain. Antiferromagnetism was found, with substantial ferromagnetic character, suggesting that the magnetic ground state is complex.
