N 52 New manganese(II) 2d-polymer with deprotonated hydroxytetrazine bridges [Text] / M. A. Kiskin [и др.] // Inorganic Chemistry Communications. - 2005. - Vol. 8, № 6. - P524-528 Рубрики: ХИМИЧЕСКИЕ НАУКИ Аннотация: A reaction of pivalate polymer [Mn(OOCCMe3)2(EtOH)]n (1) with 3-hydroxy-6-(3,5-dimethylpyrazol-1-yl)-1,2,4,5-tetrazine (2, L) in EtOH solution under inert atmosphere gives rise to an antiferromagnetic 2D-polymer [Mn(?-N,N?O-3,5-Me2C3HN2C2(O)N4)2]n (4). According to the X-ray analysis data, M(L–H)2 units form a 2D-infinite network in the lattice of compound 4 where L–H is a starting deprotonated hydroxytetrazine. The reaction of 1 with bis[3,5-(dimethylpyrazolyl)]-1,2,4,5-tetrazine (3) in MeCN solution in air results in an antiferromagnetic hexanuclear pivalate cluster Mn6(?4-O)2(?-OOCCMe3)10(L1)4 (5) where L1 is a dimethylpyrazole molecule – product of hydrolytic splitting of initial bispyrazolyltetrazine. |
