2,2'-(Diselane-1,2-di-yl)dinicotinamide N,N'-dimethyl-formamide disolvate.


ABSTRACT: The asymmetric unit of the title compound, C(12)H(10)N(4)O(2)Se(2)·2C(3)H(7)NO, contains two solvent mol-ecules and two half mol-ecules of the dinicotinamide, each of which sits on a center of symmetry passing through the middle of the Se-Se bond. In each mol-ecule, 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 mol-ecules). Inter-molecular N-H?O hydrogen bonds stablilize the crystal packing.
