Abstract
The reactions of the polymeric complex [Co(OH)n(OOCCMe3)2–n ]x (1) with 2-amino-5-methylpyridine (L1) and 2,6-diaminopyridine (L2) under anaerobic conditions at the ratio M : L = 1 : 1 afforded the binuclear complexes Co2(μ-OOCCMe3)4[η-MeC5H3N(NH2)]2 (2) and Co2(μ-OOCCMe3)4[η-C5H3N(NH2)2]2 (3), respectively, with Chinese-lantern-like structures. The reaction of the tetranuclear cobalt(ii) complex Co4(μ3-OH)2(μ-OOCCMe3)4(η2-OOCCMe3)2(EtOH)6 (4) with 2,6-diaminopyridine under anaerobic conditions at the ratio M : L2 = 2 : 1 gave rise to the antiferromagnetic tetranuclear complex Co4(μ4-O)[μ-C5H3N(NH2)2]2(μ-OOCCMe3)4(η2-OOCCMe3)2 (5) with tetradentate-bridging coordination of the oxygen atom. The structures of the compounds synthesized were established by X-ray diffraction analysis.
