A bicomplex of salicylaldehyde benzoylhydrazone ( SBH ) with Zn(II) was synthesized in ethanol and single crystals were obtained in DMSO. The compound crystallizes in the orthorhombic system with the space group  Pna 2 1 (33) and crystal data:  a  = 22.573(3)Å,  b  = 6.1208(5) Å,  c  = 17.881(2) Å,  V  = 2470.5(5) Å 3 ,  Z  = 4,  d (calc) = 1.462 g⋅cm –3 , (2633 reflections with  I  &gt; 2  σ ( I ); final  R  = 0.0509;  R  w  = 0.1099). The asymmetric unit is a nearly planar bicomplex built up from one Zn atom linked to two monodeprotonated  SBH  ligands. The compound can be described as formed of chains extended along the  b  axis. This linear polymeric character results from the linking of each asymmetric unit to two neighbouring ones via four (2x2) covalent Zn-O bonds involving three Zn atoms and four phenolic oxygens. These covalent bonds are related to the very unusual  Z  configuration of the ligand. The three-dimensional cohesion of the compound is obtained by van der Waals forces be-tween the polymeric chains.
