Crystal Structure of a Novel Cadmium Coordination Polymer Cd15(OH)4(SO4)4(L1)6(L2)12n (HL1 = 1,2,3-1H-Triazole, HL2 = 5-Methyl-1H-tetrazole)

摘要

A novel cadmium coordination polymer [Cd15(OH)4(SO4)4(L1)6(L2)12]n(HL1=1,2,3-1H-triazole,HL2=5-methyl-1H-tetrazole) has been synthesized and characterized by elemental analysis and single-crystal X-ray diffraction.The compound crystallizes in cubic Ⅰ-43d space group with a=21.5247(4),V=9972.7(3) 3,Z=4,Dc=2.360 g/cm3,Mr=3543.68,μ(MoKα)=3.298 mm-1,F(000)=6696,the final R=0.0340 and wR=0.0992 for 1909 observed reflections(Ⅰ> 2σ(Ⅰ)).The compound contains two crystallographically independent Cd coor-dination centers linked up through one L1 and two L2 bridges.The structure displays an inorganic-organic hybrid cadmium coordination polymer.
