The crystal structure of [Ni(Hbim)(3)](PTMA). 3MeOH (1) (Hbim(-) = mono diprotonated 2,2’-biimidazolate and PTMA(+) = phenyltrimethyl-ammonium cation) has been determined. The structure was consists of Ni(II) centers hexacoordinated by three 2,2’-biimidazolate (Hbim(-)) ligands in an octahedral arrangement. The crystal packing structure of complex 1 forms channel structures having the hole about similar to 9 Angstrom along the c axis.
