Abstract: In the title compound, {[NiWO4(C16H36N4)]·4H2O}n, the NiII ion lies on an inversion center and is octahedrally coordinated by four N atoms of the tetradentate macrocyclic 5,5,7,12,12,14-hexamethyl-1,4,8,11-tetraazacyclotetradecane (L) ligand in the equatorial plane and two O atoms of [WO4]2- anions in axial positions. Each [WO4]2- anion bridges two adjacent [NiL]2+ cations, forming a chain along [001]. The chains are further connected via N-H...O, O-H...O and C-H...O hydrogen-bonding interactions, generating a three-dimensional structure.
