An ammonium iron(II) pyrophosphate, (NH(4))(2)[Fe(3)(P(2)O(7))(2)(H(2)O)(2)], with a layered structure

Diammonium diaquabis(phosphato)triferrate(II), (NH(4))(2)[Fe(3)(P(2)O(7))(2)(H(2)O)(2)], was synthesized under solvo­thermal conditions at 463 K. The crystal structure, isotypic to its Mn and Ni analogues, is built from iron pyrophosphate layers parallel to (100), which are linked by ammonium ions s...

description Diammonium diaquabis(phosphato)triferrate(II), (NH(4))(2)[Fe(3)(P(2)O(7))(2)(H(2)O)(2)], was synthesized under solvo­thermal conditions at 463 K. The crystal structure, isotypic to its Mn and Ni analogues, is built from iron pyrophosphate layers parallel to (100), which are linked by ammonium ions sitting in the inter­layer space via O—H⋯O and N—H⋯O hydrogen bonds. There are two crystallographic Fe sites in the crystal structure, one at a special position (2a, [Image: see text]), the other at a general position (4e, 1). The former Fe atom on the inversion centre is coordinated by six O atoms, forming an FeO(6) octa­hedron, while the latter is coordinated by five phosphate O atoms and one water mol­ecule, forming an FeO(5)(H(2)O) octa­hedron. Each FeO(6) octa­hedron shares trans edges with two FeO(5)(H(2)O) octa­hedra, forming a linear trimeric unit. These trimers share the lateral edges of FeO(5)(H(2)O) with other trimers, forming a zigzag chain running along [010]. The zigzag chains are further linked by P(2)O(7) groups into a layered structure parallel to (100).
