title: Diaquabis(4,5-dihydro-1,2,4-triazolo
abstract: The title compound, [Ni(NCS)(2)(C(5)H(4)N(4)O)(2)(H(2)O)(2)], crystallizes in the triclinic space group P-1. The molecular unit contains two neutral molecules of 4,5-dihydro-1,2,4-triazolo[1, 5-a]pyrimidin-5-one (5HtpO) coordinated through the N atom in position 3, two thiocyanate ligands coordinated through their N atoms and two water molecules completing an octahedral environment around the Ni(II) ion, which lies on a centre of inversion. The structure is stabilized by hydrogen bonding. Distances in the coordination sphere are Ni-N3(5HtpO) 2.132 (2), Ni-O(water) 2.085 (2) and Ni-N(thiocyanato) 2.040 (2) A.
