Synthetic structural analogs of natural minerals of the averievite and yaroshevskite have been received in the course of high-temperature synthesis by method of gas transmission reactions in the threefold CuCl2-V2O5-CuO system. Important aspect of crystal structure of the synthetic averyevite is education from ions of copper of the correct symmetric grid kagome. For such structures the unique magnetic properties caused by formation of frustrated lattices and leading to emergence of effect of spin liquid are noted.
