-Di-aqua-bis-(,,'-tri-methyl-ethylenedi-amine)-nickel(II) dichloride.

In the title salt, [Ni(CHN)(HO)]Cl, the asymmetric unit is comprised of half of the complex cation and a chloride ion with the Ni atom of the cation situated about a twofold rotation axis. The six-coordinate Ni atom of the cation is connected to four N atoms from two methyl-substituted ethyelenedi-amine ligands and two water mol-ecules in a slightly distorted octa-hedral environment. The five-membered chelate ring is in a slight envelope conformation. The crystal packing features O-H⋯Cl and N-H⋯Cl inter-molecular inter-actions with the Cl ion forming weak bifurcated hydrogen bonds with nearby water mol-ecules and N-H inter-actions, leading to a three-dimensional supra-molecular network structure.
