Interaction of 3,5-dimethylpyrazole with cobalt(II) carboxylates containing coordinated 1,10-phenanthroline or 2,2′-dipyridyl
摘要:
The reaction of Co-3(mu-OOCBu (t) )(6)(NEt3)(2) with 1,10-phenanthroline or 2,2'-dipyridyl in benzene at room temperature yields L2Co2(mu-OH2)(mu-OOCBu (t) )(4) complexes (L-2 = Phen (1a) and Dipy (1b)). The reaction of n1a (1b) with 3,5-dimethylpyrazole gives a mixture of L2Co(Hdmpz)(2)(OOCBu (t) )(2) complexes (2a, 2b) and L2Co(Hdmpz)(OOCBu (t) )(2) (3a, 3b), and their yield is determined by the ratio of the initial reagents. As distinct from pivalates, for cobalt(II) phenanthroline-benzoate, only the (Phen)Co(Hdmpz)(2)(OOCPh)(2) complex (4) has been isolated. The structures of the synthesized compounds have been determined by X-ray crystallography.
