| Abstract: The title complex, [Co(L)(H2O)]n, 1, where H2L=3-(carboxymethoxy)-2-naphthoic acid, was synthesized through hydrothermal synthesis and its crystal structure was determined by X-ray diffraction analysis. The crystal is monoclinic, space group P21 with a= 0.505 87(7) nm，b=0.942 88(12) nm，c=1.234 03(16) nm，β=95.015(9)°，V=0.586 35(13) nm3，Z=2，Mr=321.14，Dc=1.819 g·cm-3，μ=1.487 mm-1，F(000)=326，Rint=0.023 8，R1=0.022 8，wR2=0.053 2, and the Flack parameter is 0.026(13). In the complex, the cobalt atom is six-coordinated by six oxygen atoms, completing an octahedral geometry. The molecules are connected to form a 2D layer structure bridged by 3-(carboxymethoxy)-2-naphthoic acid. The cyclic voltammetric behavior of the complex was also studied. CCDC: 826094. |
