摘要：

Magnetic measurements on CoTa//2O//6 and NiTa//2O//6 are reported. The samples were obtained by a chemical transport reaction using chlorine as the transporting agent. Susceptibility data show, in contrast to former investigations, long-range magnetic ordering at T//c equals 6. 64 K (Co) and 10. 3 K (Ni). Broad maxima in the magnetic susceptibility above T//c are attributed to low-dimensional short-range magnetic ordering. The relevancy of these observations for the chemistry of the title compounds is discussed.
