Abstract: | Colourless crystals of Hg2(Mmt)(Dmt)2](NO3)(H2O) were obtained from a reaction of mercuric nitrate with monomethyl‐ and dimethyl‐1,2,4‐triazolate (Mmt? and Dmt?, respectively). In the crystal structure (monoclinic, C2/c (no. 15), a = 2579.4(4), b = 1231.1(2), c = 1634.8(2) pm, β = 128.32(1)°, V = 4073.3(11)·106·pm3, Z = 8, R1 I0 > 2σ(I0)]: 0.0355), half of the mercuric ions are essentially two‐coordinate (Hg–N: 210‐215 pm), the other half are tetrahedrally surrounded by N‐donor atoms (Hg–N: 221, 225 pm) of the Mmt? and Dmt? anions. These three‐N ligands construct a three‐dimensional framework. |
