摘要：

The synthesis, crystal, and molecular structure of Co(Cx)3Na6H2O are reported. The Cobalt(II) compound crystallizes in the trigonal system, space group R 3 with Z = 6, in a cell of dimensions a = 18.688(7) (angstrom), c = 20.142(6) angstrom. Least-squares refinement of 1331 reflections [I greater-than-or-equal-to 3BAR-sigma(I)] gave a final R = 0.088 for all observed reflections. The structure consists of anionic monomeric units of (Co(Cx)3-) and sodium cations. Three Cinoxacinate ions are chelated through O(ceto) and O(carbox) atoms. The Co(II) ion positioned on the third axis is bonded to six oxygen atoms in a slightly distorted octahedral environment.
