摘要

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 Cd^II 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 Cd^II 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 Cd^II atom through one carboxylate oxygen, the nitrogen, and both hydroxyl oxygen atoms and bridges the second, six-coordinate trigonal prismatic Cd^II 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.
