✦ Synopsis

Anhydrous manganese(H), cobalt(H) and zinc(II) cyanoacetates have been prepared and characterized using spectroscopic, magnetic and X-ray powder photographic methods. The metal atoms in these octahedral polymeric compounds are surrounded by bridging and/or chelating carboxylate groups, together with N-bonded cyano-groups. l%ese cyanoacetates react with pyridine and 2,2'bipyridyl to afford the octahedral complexes M(0, CCH2CN)2(py)2, (M = Mn, Co or Zn), and Zn(Oz-CCHKN)z(bipy) which contain bidentate carboxylate groups, and M(02CCH2CN)2(bipy)2, (M = Mn or Co), which contain unidentate carboxylate groups. Unlike the parent cyanoacetates, no metalcyano-nitrogen interactions occur in these complexes
