Crystal structure of (NH(4))(2)[Fe(II) (5)(HPO(3))(6)], a new open-framework phosphite

Di­ammonium hexa­phosphito­penta­ferrate(II), (NH(4))(2)[Fe(5)(HPO(3))(6)], was synthesized under mild hydro­thermal conditions and autogeneous pressure, yielding twinned crystals. The crystal structure exhibits an [Fe(II) (5)(HPO(3))(6)](2−) open framework with NH(4) (+) groups as counter-cations....

description Di­ammonium hexa­phosphito­penta­ferrate(II), (NH(4))(2)[Fe(5)(HPO(3))(6)], was synthesized under mild hydro­thermal conditions and autogeneous pressure, yielding twinned crystals. The crystal structure exhibits an [Fe(II) (5)(HPO(3))(6)](2−) open framework with NH(4) (+) groups as counter-cations. The anionic skeleton is based on (001) sheets of [FeO(6)] octa­hedra (one with point-group symmetry 3.. and one with .2.) linked along [001] through [HPO(3)](2−) oxoanions. Each sheet is constructed from 12-membered rings of edge-sharing [FeO(6)] octa­hedra, giving rise to channels with a radius of ca 3.1 Å in which the disordered NH(4) (+) cations are located. The IR spectrum shows vibrational bands typical for phosphite and ammonium groups.
