Figure 4
(a) The CuII ions in (I) depicted as small spheres. Note that the polymeric chains at the consecutive z levels (0, , ½, ) of the unit cell propagate in perpendicular directions. Note also the crosslinking between the different polymers by the formate anions. (b) An expanded view of the octahedral environment of the copper(II) ion. The long trans-axial Cu—O bonds in the distorted octahedron are indicated by asterisks. |
