摘要

In the title coordination polymer, [Zn2(C6H10N3)3(NO3)]n, two independent ZnII?ions are tetra-hedrally coordinated by the anionic ligands,?viz. 2-[(di-methyl-amino)-meth-yl]imidazolate or nitrate ions. One ZnII?ion is coordinated by the imidazolate N atoms of three anions and an O atom of the nitrate ion. The second ZnII?ion is coordinated by imidazolate N atoms of three anions and one amino N atom of one such ligand. The 2-[(di-methyl-amino)-meth-yl]imidazolate anions are bridging the ZnII?ions to form a helical chain structure along [001]. The chains are further linked by the bridging ligands into a three-dimensional framework structure. The nitrate anion is disordered over two sets of sites and was refined with two pairs of three O atoms using half-occupancy for each O atom.
