Poly[(μ(6)-benzene-1,3,5-tricarboxyl­ato-κ(6) O (1):O (1′):O (3):O (3′):O (5):O (5′))tris­(N,N-dimethyl­formamide-κO)tris­(μ(3)-formato-κ(2) O:O′)trimagnesium(II)]

The title complex, [Mg(3)(CHO(2))(3)(C(9)H(3)O(6))(C(3)H(7)NO)(3)](n), exhib­its a two-dimensional structure parallel to (001), which is built up from the Mg(II) atoms and bridging carboxyl­ate ligands (3 symmetry). The Mg(II) atom is six-coordinated by one O atom from a dimethyl­formamide mol­ecule, two O atoms from two μ(6)-benzene-1,3,5-tricarboxyl­ate ligands and three O atoms from three μ(3)-formate ligands in a distorted octa­hedral geometry.
