摘要

The recently investigated compound Co6O2[TeO4(CoAsO5)(2) marks the first occurrence of a tellurate-arsenate additionally revealing the hitherto unknown pyro-cobaltoarsenate group CoAsO7. One oxygen is exclusively connected to octahedrally coordinated cobalt. It is shown that the structure of Co6O2[TeO4(CoAsO5)(2)] can be derived step by step from the rock salt structure of CoO. Magnetic measurements using the Faraday technique reveal Curie-Weiss behaviour between 88 and 325 K. Low temperature measurements by a SQUID magnetometer show antiferromagnetism and a relatively low NEEL temperature of 5 K compared to other Co(II) compounds. [References: 16]
