DMF, gives the complex [Ni2L1(NCS)2(DMF)] (5). An acyclic complex, [Ni2L2(C3H3N2)](CF3SO3)2 (6), is formed by reaction of two equivalents of nickel(II) ions with 2,6-diformyl-4-methylthiophenolate, pyrazole and two equivalents of 2-(2-aminoethyl)pyridine. Single crystal X-ray diffraction studies of 4 and 5 revealed differing environments for the nickel(II) ions within the macrocycle: in the case of
