Original Paper


A new nickel(II) complex formulated as, trans-[Ni(amp)2(SCN)2(H2O)2]·2H2O (1), (amp = 2-aminopyrimidine) has been synthesized and characterized by elemental analysis, IR spectroscopy, its molecular and crystal structures were determined by X-ray crystal structure analysis and its thermal stability by TGA/DTA methods. 1 is a neutral complex and the central atom sits on an inversion center and is coordinated by two endocyclic nitrogen atoms of two 2-aminopyrimidine heterocycles, two oxygen atoms of two water molecules and two nitrogen atoms of SCN ions. 2-aminopyrimidine molecules, thiocyanate ions and water molecules are in trans position. Thermal methods confirm two co-crystallized water molecules in 1. π–π stacking interactions and extensive O–H···O, O–H···N, O–H···S and N–H···N hydrogen bonds contribute to the formation of a three-dimensional supramolecular structure. Crystal data for complex at 120 K: triclinic, space group P-1, a = 7.2026(14), b = 7.8332(15), c = 9.0270(17) Å, α = 67.694(3), β = 72.732(4), γ = 77.012(4), Z = 1, R 1 = 0.0323.
