title: N,N-Diisopropylidene-pyrazine-2,5-dicarbohydrazide dihydrate.
abstract: In the title compound, C(12)H(16)N(6)O(2)·2H(2)O, the organic mol-ecule, except for the methyl H atoms, is essentially planar, the r.m.s. deviation from planarity being 0.044 Å. The crystal structure is stabilized by inter-molecular O-H⋯O and O-H⋯N hydrogen bonds which form chains.
