Poly[bis-(μ(6)-benzene-1,3,5-tricarboxyl-ato-κ(7)O(1),O(1'):O(1'):O(3):O(3'):O(5):O(5'))tetra-kis-(dimethyl-formamide-κO)trimagnesium(II)].
The asymmetric unit of the polymeric title compound, [Mg(3)(C(9)H(3)O(6))(2)(C(3)H(7)NO)(4)](n), contains three Mg(II) ions bridged by carboxyl-ate O atoms from two fully deprotonated benzene-1,3,5-tricarboxyl-ate (BTC) trianions and four metal-coordinated dimethyl-formamide (DMF) mol-ecules. One Mg(II) ion is octa-hedrally coordinated by six carboxyl-ate O atoms. The other two cations are each octa-hedrally coordinated by four carboxyl-ate O atoms and two O atoms donated by two DMF mol-ecules: in one, the DMF mol-ecules are cis and in the other they are trans. The three Mg(II) octa-hedra form clusters, which are bridged by the BTC trianions, generating a three-dimensional structure.
