Аннотация:In this work the compounds Cu2(CCl3COO)3(OH)(H2O)5 and Co(NO3)3(NO2 - C7H6N2) were chosen as objects of the research. Their magnetic properties were not explored earlier. The magnetic subsystem of the first one is introduced by copper ions (isolated ions and linear chains with the ratio of 1:1 by copper ions). In the second compound magnetism is caused by cobalt chaines. These structures let us to suppose the existence of 1D-magnetism in our compounds.
