Hydrothermal Synthesis, Crystal Structure and Electrochemical Properties of a Cobalt(II) Complex Constructed by 3-(carboxymethoxy)-2-naphthoic Acid

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 P2(1) with a=0.505 87(7) nm, b=0.942 88(12) nm, c=1.234 03(16) nm, beta=95.015(9), V=0.586 35 (13) nm(3), Z=2, M-r=321.14, D-c=1.819 g.cm(-3), mu=1.487 mm(-1), F (000)=326, R-int=0.0238, R-1=0.0228, wR(2)=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.
