Crystal structures and theoretical calculations on the ion pairs of two types of heterometallic \(NiSnII)-Sn-II\\Sn-IV\ (type I) and \(NiSnII)-Sn-II\\Sn-II\ (type II) complex salts synthesized from the self-assembly reaction of the Schiff base N,N -ethylenebis(3-methoxysalicylaldimine) (H2L1), N,N -ethylenebis(3-ethoxysalicylaldimine) (H2L2), or N,N -bis(3-methoxysalicylidene)-1,2-cyclohexanediamine (H2L3) with an adequate mixture of NiCl2 center dot 6H(2)O, SnCl2, and SnCl4:5H(2)O are presented. The heterometallic cation [(NiSnL)-Sn-II-L-II(C
