摘　　要：One new Mn(Ⅱ)coordination polymer,[Mn(Htia)_(2)(H_(2)O)_(2)]_(n)·2nH_(2)O(1,H_(2)tia=4-(1,2,4-triazol-1-yl)isophthalic acid)has been synthesized in mixed solvents under solvothermal conditions.Further characterizations including single-crystal XRD,elemental analysis,IR spectroscopy,thermogravimetric analysis and powder XRD were performed to verify the structure.Complex 1 displays a one-dimensional(1D)chain and is similar to a reported Mn(II)complex 2{[Mn(Htta)_(2)(H_(2)O)_(2)]·2H_(2)O}_(n).It crystallizes in triclinic P1 space group,with a=7.5557(3),b=7.5974(3),c=11.8448(4)Å,α=90.088(1)°,β=95.863(1)°,γ=113.668(1)°,V=618.81(4)Å^(3),Z=1,M_(r)=591.36 g/mol,D_(c)=1.587 mg/m^(3),μ=0.609 mm^(-1),F(000)=303,GOOF=1.062,the final R=0.0359and w R=0.0818 for 4272 observed reflections with I>2σ(I).Based on two similar structures,Hirshfeld surface analysis confirmed both structures are mainly stabilized by O···H/H···O and C···H/H···C hydrogen bonds.Further,weak ferromagnetic behaviors between adjacent Mn(II)ions in 1D chain are obtained.
