(Aqua) O-H center dot center dot center dot N hydrogen-bonding interactions induce the formation of one-dimensional helical [Zn(L)(bpmb)(H2O)](n) chains which are interlinked through (aqua)O-H center dot center dot center dot O hydrogen-bonding interactions, producing two-dimensional corrugated sheets.
