An octahedral cobalodioxime of a new tetradentate dioxime ligand, 3,8-dimethyl-4,7-diazadeca-3,7-diene-2,9-dionedioxime (LH2) and its unprecedented H-bonded self-assembling have been reported. The diamagnetic bioinorganic Cl2Co(LH) (1) unit of zero dimensions assembles to infinite 1D helical strand by novel head-on H-bonding helices. Interstrand facial H-bonding results the 2D helices and interhelices lateral H-bonding (oxime-oxime and Cl-H(CH2)) constructs the 3D framework. The H-bonding effect has been established in solution also and investigated by H-1 NMR spectra in DMSO-d(6) and CDCl3 solvents.
