โฆ Synopsis
Benzilic and mandelic ester complexes 423 manganese(II), cobalt(II), complexes of benzilic and Summary Solid metal complexes of benzilic and mandelic esters have been prepared and their structure elucidated using vis., i.r., n.m.r, and e.s.r, spectra. The results of elemental analysis are commensurate with the proposed formulae. Spectral studies indicate that the Ni complexes are octahedral, whereas the Co and Cu analogoues are distorted octahedral.
