Two new alkaline earth metal coordination polymers constructed from the deriva-tive of 1,2,4-triazole are presented herein,namely,{[Sr(AmTAZAc)2(H2O)]}(1) and {[Ba(AmTAZAc)2(H2O)]}(2)(AmTAZAc = 3-amino-1H... Two new alkaline earth metal coordination polymers constructed from the deriva-tive of 1,2,4-triazole are presented herein,namely,{[Sr(AmTAZAc)2(H2O)]}(1) and {[Ba(AmTAZAc)2(H2O)]}(2)(AmTAZAc = 3-amino-1H-1,2,4-triazole-5-carboxylate),which have been synthesized by using the layering method and structurally characterized by elemental analysis,IR,and single-crystal X-ray diffraction.Complexes 1 and 2 are isostructural,and both crystallize in the orthorhombic system,space group Fdd2.X-ray structural analysis shows that 1 or 2 has an intriguing 3-D infinite network of(318.438.510) topology based on a 2-D sheet structure of(4,4) net.The result shows that noncovalent interactions play an important role in strengthening the whole structures of the compounds. 展开更多
