Abstract

The asymmetric unit of the title compound, C12H10N4O2Se2·2C3H7NO, contains two solvent mol­ecules and two half mol­ecules of the dinicotinamide, each of which sits on a center of symmetry passing through the middle of the Se—Se bond. In each mol­ecule, the two pyridyl groups and diseleno group are approximately coplanar (r.m.s. deviations from planarity for all non-H atoms = 0.011 and 0.008 Å in the two mol­ecules). Inter­molecular N—H⋯O hydrogen bonds stablilize the crystal packing.
