The paper describes the synthesis of 1,2,3-triazole derivatives of bis (1,2-dicarbollide) cobalt using 1,3-dipolar cycloaddition reaction of [3 +2] cycloaddition, namely the «click»-methodology. It is shown that the interaction of azido derivatives of cobalt bis (1,2-dicarbollide) with derivatives of cobalt bis (1,2-dicarbollide) with a terminal acetylene group leads to 1,2,3-triazoles with metal carboran substitutes at sites 1 and 4. The possibility is shown of introducing a halogen into the metal carboran substitute of the synthesized 1,2,3-triazoles.
