| Popis: | The reaction of 𝑁,𝑁-bis(2-hydroxyethyl)glycine (bicine; bicH3) with Cd(O2CPh)2⋅2H2O in MeOH yielded the polymeric compound [Cd2(O2CPh)2(bicH2)2]n(𝟏). The complex crystallizes in the tetragonal space group 𝑃41212. The lattice constants are 𝑎=𝑏=12.737(5) and c=18.288(7) Å. The compound contains chains of repeating {Cd2(O2CPh)2(bicH2)2} units. One CdII atom is coordinated by two carboxylate oxygen, four hydroxyl oxygen, and two nitrogen atoms from two symmetry-related 2.21111 (Harris notation) bicH2− ligands. The other CdII atom is coordinated by six carboxylate oxygen atoms, four from two bicH2− ligands and two from the monodentate benzoate groups. Each bicinate(-1) ligand chelates the 8-coordinate, square antiprismatic CdII atom through one carboxylate oxygen, the nitrogen, and both hydroxyl oxygen atoms and bridges the second, six-coordinate trigonal prismatic CdII center through its carboxylate oxygen atoms. Compound 1 is the first structurally characterized cadmium(II) complex containing any anionic form of bicine as ligand. IR data of 1 are discussed in terms of the coordination modes of the ligands and the known structure. |
