By using Co(NH3)63+ as the template,a new complex HNU-38 was synthesized under hydrothermal reaction through the adoption of H3BTC and CI-as the ligands (H3BTC =1,3,5-benzenetricarboxylic acid).HNU-38 crystallized in the monoclinic system,P21/c space group with a =9.9696(3),b =17.0580(6),c =16.5263(6) (A),β =100.400(2)°,Z =4,V =2764.31(16) (A)3,Mr =883.63,Dc =2.123 g/cm3,F(000) =1736,S =0.920,R =0.0358 and wR =0.0838 (I > 2σ(I)).In HNU-38,the Cd2+ and BTC3-were linked together to form layers with Cl-serving as the pillar.It should be noted that (H2O)n chains were found in the channels and play a co-templating role along with the Co(NH3)63+ cations in HNU-38,and the proton conduction properties were investigated.
