New manganese (II) 2d-polymer with deprotonated hydroxytetrazine bridges

Abstract

A reaction of pivalate polymer [Mn(OOCCMe 3) 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(μ- N, N′ O-3,5-Me 2C 3HN 2C 2(O)N 4) 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 Mn 6(μ 4-O) 2(μ-OOCCMe 3) 10(L 1) 4 ( 5) where L 1 is a dimethylpyrazole molecule – product of hydrolytic splitting of initial bispyrazolyltetrazine.
