چکیده
In the title complex, [Zn(NCO)(2)(C(7)H(8)N(4))(2)], the Zn(II) ion exhibits a distorted tetra-hedral coordination geometry. The coordination environment is formed by two 5,7-dimethyl-1,2,4-triazolo[1,5-a]pyrimidine (dmtp) ligands, coordinated through the N atom in position 3, and two cyanate anions inter-acting by their N atoms. Supra-molecular dimers are generated by stacking inter-actions between the pyrimidine rings of two ligands related by an inversion center [centroid-centroid distance = 3.5444 (18) Å].

In the crystal structure of the title 1:2 adduct, [Zn(2)(NCS)(4)(C(4)H(8)N(4))(2)]·2[Zn(NCS)(2)(C(4)H(8)N(4))(2)] or (Ia)·2(Ib), each Zn(II) atom is coordinated in a distorted tetra-hedral geometry by four N atoms from two triazole rings of two 4-amino-3,5-dimethyl-1,2,4-triazole (admt) ligands and two NCS(-) ligands. In (Ia), double N(1):N(2)-bridging admt ligands connect two Zn(II) atoms, for...
