| Abstract: A Coordination polymer [NaMn(pic)3]n (1) (picH=picolinic acid) has been synthesized by hydrothermal synthesis and structurally characterized by single crystal structure determination. 1 crystallizes in the orthorhombic space group Pbca, a=1.251 9(4) nm, b=1.715 8(8) nm, c=1.754 7(7) nm, V=3.769(6) nm3, Mr=444.24, Dc=1.566, F(000)=1 800, R1=0.024 8 and wR2=0.075 1 for I>2σ(I). According to the crystal structure, each Mn(Ⅱ) ion of 1 is six-coordinated with three oxygen and three nitrogen atoms from three pic anions to form a distorted dodecahedron. Each Na+ ion of 1 is penta-coordinated with two oxygen atoms from a pic anion and three oxygen atoms from three pic anions of diffrent unit to form a distorted tetragnal pyramid. The three-dimensional coordination polymer 1 is connected through Na+ ion. CCDC: 683029. |
