Abstract:
The title complex, ([Fe(C(4)H(4)O(4))(H(2)O)(4)])(n), is an infinite polymeric compound bridged by the succinate dianion. Two carboxylate groups coordinate in a monodentate manner to the Fe(II) atom, in a trans fashion, with an O-Fe-O bond angle of 175.72 (6) degrees and Fe-O distances of 2.0886 (14) and 2.1008 (15) A. One of the uncoordinated carboxylate O atom forms an intramolecular hydrogen bond with a coordinated water molecule. Extensive hydrogen bonding between parallel polymeric complex chains results in a three-dimensional supramolecular structure.
