Abstract
Molecules of 2-chloro-N-(2-nitrophenyl)nicotinamide, C12H8ClN3O3, are linked by two C-H
O hydrogen bonds into a chain of edge-fused 
(14) and 
(24) rings. In 2-chloro-N-(3-nitrophenyl)nicotinamide monohydrate, C12H8ClN3O3·H2O, the molecules are linked by a combination of N-HO, O-HO and O-HN hydrogen bonds into a chain of edge-fused rings containing two distinct types of (16) ring. In 2-chloro-N-(4-nitrophenyl)nicotinamide, C12H8ClN3O3, which crystallizes with Z‘ = 2 in space group P21/n, the molecules are linked by two N-HN hydrogen bonds into simple 
(12) chains.
