description: (Mg(HCOO)2)3C3NH7O crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional and consists of four n,n-dimethylformamide molecules and one Mg(HCOO)2 framework. In the Mg(HCOO)2 framework, there are four inequivalent Mg2+ sites. In the first Mg2+ site, Mg2+ is bonded to six O2- atoms to form a mixture of edge and corner-sharing MgO6 octahedra. The corner-sharing octahedra tilt angles range from 64–65°. There are a spread of Mg–O bond distances ranging from 2.10–2.14 Å. In the second Mg2+ site, Mg2+ is bonded to six O2- atoms to form corner-sharing MgO6 octahedra. The corner-sharing octahedral tilt angles are 64°. There are four shorter (2.08 Å) and two longer (2.18 Å) Mg–O bond lengths. In the third Mg2+ site, Mg2+ is bonded to six O2- atoms to form edge-sharing MgO6 octahedra. There are a spread of Mg–O bond distances ranging from 2.05–2.15 Å. In the fourth Mg2+ site, Mg2+ is bonded to six O2- atoms to form corner-sharing MgO6 octahedra. The corner-sharing octahedral tilt angles are 65°. There are a spread of Mg–O bond distances ranging from 2.07–2.16 Å. There are six inequivalent C+1.11+ sites. In the first C+1.11+ site, C+1.11+ is bonded in a trigonal planar geometry to one H1+ and two O2- atoms. The C–H bond length is 1.11 Å. There is one shorter (1.25 Å) and one longer (1.29 Å) C–O bond length. In the second C+1.11+ site, C+1.11+ is bonded in a trigonal planar geometry to one H1+ and two O2- atoms. The C–H bond length is 1.11 Å. There is one shorter (1.25 Å) and one longer (1.29 Å) C–O bond length. In the third C+1.11+ site, C+1.11+ is bonded in a trigonal planar geometry to one H1+ and two O2- atoms. The C–H bond length is 1.10 Å.

The C–H bond length is 1.11 Å. There is one shorter (1.26 Å) and one longer (1.29 Å) C–O bond length. In the fifth C+1.11+ site, C+1.11+ is bonded in a trigonal planar geometry to one H1+ and two O2- atoms. The C–H bond length is 1.11 Å.

The C–H bond length is 1.11 Å. There is one shorter (1.25 Å) and one longer (1.29 Å) C–O bond length. There are six inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one C+1.11+ atom. In the second H1+ site, H1+ is bonded in a single-bond geometry to one C+1.11+ atom. In the third H1+ site, H1+ is bonded in a single-bond geometry to one C+1.11+ atom. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one C+1.11+ atom.
