The molecules of 2,6‐dichlorobenzohydrazide, C 7 H 6 Cl 2 N 2 O, are linked into simple chains by a single N—H⋯O hydrogen bond, while in the isomeric compound 2,4‐dichlorobenzohydrazide, the molecules are linked by N—H⋯N and N—H⋯O hydrogen bonds into complex sheets comprising an inner polar layer sandwiched between two non‐polar layers. In 4‐amino‐2‐chlorobenzohydrazide monohydrate, C 7 H 8 ClN 3 O·H 2 O, the components are linked into a three‐dimensional framework by a combination of O—H⋯O, O—H⋯N, N—H⋯N and N—H⋯O hydrogen bonds, and in 2‐nitrobenzohydrazide, C 7 H 7 N 3 O 3 , a three‐dimensional framework is formed by a combination of N—H⋯N and N—H⋯O hydrogen bonds
