Organically templated linear metal sulfites

Author affiliations


Organically-templated linear zinc and manganese sulfites have been prepared under mild reaction conditions and structurally characterized by single crystal X-ray diffraction. The linear zinc sulfites, with the compositions, [(C3H10N)2][Zn(SO3)2], 1, [C3H12N2][Zn(SO3)2], 2, [C4H14N2][Zn(SO3)2], 3, [C6H18N2][Zn(SO3)2], 4 and [C4H12N2][Zn(SO3)2]·H2O, 5 possessing chain topologies consist of ZnO4 tetrahedra and SO3 pyramidal units forming four-membered rings which are connected through their vertices giving rise to 1D-chain structures. The linear manganese sulfite 6, with the composition [C4H12N2][Mn(SO3)2(H2O)2]·2H2O has kronkite type topology through corner sharing of four-membered rings formed by the MnO6 octahedron and SO3 pyramidal units. In all these structures the amine molecules are sitting between the interchain spaces. The compounds have been characterized by powder X-ray diffraction, infrared spectroscopy and thermogravimetric analysis.
