Abstract
The cross-linked chain cobalt oxychloride Ba5Co5ClO13 is reported. Single c rystals were obtained by a flux method with BaCl2. A hexagonal unit cell (P 6(3)/mmc, a = 5.6980(8) Angstrom and c = 24.469(5) Angstrom) was found. The + 3 and + 4 valence cobalt ions were formally distributed into octahedral and tetrahedral sites coordinated by oxide ions. The compound was electrica lly insulating with a gap of 0.25 eV along the chain. Antiferromagnetism wa s found, with substantial ferromagnetic character, suggesting that the magn etic ground state is complex. (C) 2001 Academic Press.
