• X-ray structure
• Heterogeneous catalysis
• Henry reaction

A new cyclic binuclear Ni(II) complex, [Ni-2(H2L)(2)] center dot 4MeOH (1), has been synthesized using the Schiff base N%26apos;(1),N%26apos;(3)-bis(2-hydroxybenzylidene)malonohydrazide (H4L). The X-ray crystal structure of 1 shows that the ligand coordinates in the dianionic keto form (H2L2-) via mutual sharing of two Ni(II) ions. Complex 1 acts as a heterogeneous catalyst for the Henry reaction in water. A maximum conversion of ca. 93% was obtained under optimized conditions.
