N 2,N 2′-Bis(3-nitro­benzyl­idene)pyridine-2,6-dicarbohydrazide dimethyl­formamide disolvate trihydrate

Abstract

In the title compound, C(21)H(15)N(7)O(6)·2C(3)H(7)NO·3H(2)O, the N(2),N(2')-bis-(3-nitro-benzyl-idene)pyridine-2,6-dicarbohydrazide and one water mol-ecule are located on a twofold rotation axis. The mol-ecules are connected by hydrogen bonds. One dimethylformamide molecule is disordered over two positions; the site occupancy factors are ca 0.8 and 0.2.
