A chain of edge-fused rings generated by the combination of an N—H⋯O hydrogen bond and an iodo–nitro interaction in 2-iodo­benz­aldehyde 4-nitro­phenyl­hydrazone versus ­disordered and effectively isolated mol­ecules in 2-iodo­benz­aldehyde 2,4-di­nitro­phenyl­hydrazone

Part of the crystal structure of (II

), showing the formation of a molecular ladder along [021]. For the sake of clarity, H atoms bonded to C atoms have been omitted. Atoms marked with an asterisk (*), hash (#), dollar sign ($) or ampersand (&) are at the symmetry positions ( $[{{3}\over{2}}]$ − x, 1 + y, $[{{1}\over{2}}]$ + z), (x, 2 + y, 1 + z), ( $[{{3}\over{2}}]$ − x, 3 + y, $[{{3}\over{2}}]$ + z) and ( $[{{3}\over{2}}]$ − x, −1 + y, − $[{{1}\over{2}}]$ + z), respectively.
