Di-chloridotetra-kis-(3-meth-oxy-aniline)nickel(II).

The reaction of nickel(II) chloride with 3-meth-oxy-aniline yielded di-chlorido-tetra-kis-(3-meth-oxy-aniline)nickel(II), [NiCl 2 (C 7 H 9 NO) 4 ], as yellow crystals. The Ni II ion is pseudo-octa-hedral with the chloride ions trans to each other. The four 3-meth-oxy-aniline ligands differ primarily due to different conformations about the Ni-N bond, which also affect the hydrogen bonding. Inter-molecular N-H⋯ Cl hydrogen bonds and short Cl⋯Cl contacts between mol-ecules link them into chains parallel to the b axis.
