Dimethyl hydrazine-1,2-dicarboxyl-ate-triphenyl-phosphine oxide (1/1)

Abstract

In the crystal structure of the title compound, C 4H 8N 2O 4·C 18H 15OP, two triphenyl-phosphine oxide mol-ecules and two dimethyl hydrazine-1,2- dicarboxyl-ate mol-ecules are connected via N - H⋯O hydrogen bonds of moderate strength and are related via a twofold rotational axis. Weak Car - H⋯ O contacts strengthen the crystal structure. © Doboszewski et al. 2011.
