Abstract:
The asymmetric unit of the title compound, [Fe(C(9)H(4)O(6))(C(12)H(8)N(2))(H(2)O)](n), contains one Fe(II) cation, one 5-carboxy-benzene-1,3-dicarboxyl-ate dianion (Hbtc), one 1,10-phenanthroline (phen) ligand and one water mol-ecule. The Fe(II) centre displays a distorted octa-hedral geometry, being surrounded by one phen ligand, two μ(2)-O atoms of two carboxyl-ate groups from two Hbtc ligands, one O atom from one carboxyl-ate of another Hbtc ligand and one terminal water mol-ecule. One carboxyl-ate group ligates two Fe(II) cations in a μ(1,1) mode, while the other carboxyl-ate groups bonds to only one Fe atom. The crystal structure is stabilized by O-H⋯O hydrogen bonds.
