Synthesis, Crystal Structure and Luminescence of One CdII Coordination Polymer with Bifunctional Zwitterionic Ligand
摘要:
One coordination polymer with bifunctional zwitterionic ligand bearing both carboxylate and tetrazolate groups, [Cd(L1)(N3)]n·nH2O (1, L1=1-(carboxylatomethyl)-4-(5-tetrazolato)pyridinium], has been in situ hydrothermally synthesized and structurally characterized. Compound 1 crystallizes in monoclinic with C2/m space group, a=21.8038(17), b=7.6087(6), c=7.8342(6) Å, β=106.166(2)°, V=1248.29(17) Å3, Z=4, Mr=376.62, Dc=2.004 g·cm-3, F(000)=736, μ=1.772 mm-1, Rint=0.0217, S=1.088, the final R=0.0415 and wR=0.1128 for 1020 observed reflections with I>2σ(I). The compound exhibits two-dimensional coordination sheets, in which infinite anionic [Cd(CN4)(N3)(OCO)]n chains with the tricomponent (μ-azide)(μ-tetrazolate)(μ-carboxylate) bridges are cross-linked by cationic 1-methylenepyridinium spacers of the L1 ligand. This compound in the solid state exhibits blue luminescence assignable to intraligand transitions.
