trans-Diaquabis(N,N,N'-trimethylethylenediamine)- nickel(II) dichloride
In the title salt, [Ni(C5H12N2)2(H2O)2]Cl2, the asymmetric unit is comprised of half of the complex cation and a chloride ion with the NiII atom of the cation situated about a twofold rotation axis. The six-coordinate NiII atom of the cation is connected to four N atoms from two methyl-substituted ethyelenediamine ligands and two water molecules in a slightly distorted octahedral environment. The five-membered chelate ring is in a slight envelope conformation. The crystal packing features O—H⋯Cl and N—H⋯Cl intermolecular interactions with the Cl− ion forming weak bifurcated hydrogen bonds with nearby water molecules and N—H interactions, leading to a three-dimensional supramolecular network structure.
