Aqua­{N,N-dimethyl-N′-[1-(2-pyrid­yl)ethyl­idene]ethane-1,2-diamine-κ(3) N,N′,N′′}bis­(thio­cyanato-κN)nickel(II)

In the title compound, [Ni(NCS)(2)(C(11)H(17)N(3))(H(2)O)], the Ni(II) ion is six-coordinated by the N,N′,N"-tridentate Schiff base N atoms, two cis-positioned N-bound isothio­cyanate groups and one water mol­ecule. In the crystal, O—H⋯S hydrogen bonds link adjacent mol­ecules into infinite layers parallel to the ac plane. The layers are further connected into a three-dimensional network via C—H⋯π inter­actions. The –CH(2)–N(CH(3))(2) fragment is disordered over two sets of sites in a 0.556 (5):0.444 (5) ratio.
