Abstract

4, 6-Dimethoxy-3-methyldihydrotriazine-2-one (1) undergoes a single-crystal to single- crystal reversible phase transformation at 319 K. The low-temperature phase crystallizes in monoclinic space group P21/n with two crystallographically independent molecules in the asymmetric unit. The high-temperature phase is obtained by heating a single crystal of the low-temperature phase. This phase is orthorhombic, space group Pnma, with the ...
