Halide-bridged polymers of divalent metals with donor ligands – structures and properties

“…3.9 Å for edge-sharing, cf. Table 1, and to 3.58 Å in the "almost" face-sharing pyridazine complex [101], reflecting the same trend as the Cd(II) polymers mentioned above.…”

“…Two vicinal nitrogen atoms of the heterocyclic ligands pyridazine [101,102], 4-amino-3-methyl-1,2,4-triazole [103], 1,2,4-triazolato [104] or tetrazol [105] may play that role as well as an O,O -carboxylato group [106][107][108][109]. Straightforward distance criteria underline the efficiency of a vicinal diatomic bridge such as pyridazine.…”
