We have demonstrated synthesis of boroxine networks by condensation of tetrahydroxydiboron. The network material was obtained in quantitative yield by microwave-assisted heating of N,N-dimethylacetamide. The material had a crystalline structure and good stability. In addition, the material could be easily decomposed to the monomer by water addition.
