The complex crystallizes in monoclinic system, P21/n space group with a=7.500(3) Å, b=8.788(3) Å, c=16.429(6) Å, β=93.395(5)°, D c =1.269gcm−3, μ=0.930mm−1, V=1080.9(6) Å3, Z=2. The central NiII atom is in a square-planar coordination geometry formed by four N atoms of two DACH chelated ligands. The notable feature of the title compound resides in the formation of a three-dimensional network through hydrogen bonds between the [Ni(DACH)2]2+ cations, the CH3COO− counter anions and the guest water molecules trapped in the crystal lattice.
