“…Metal phosphonates have applications in many ®elds of chemistry, e.g. in catalysis and ion exchange (Bhardwaj et al, 1993;Alberti et al, 1996). The ®rst structurally studied complex of phosphonoacetic acid (H 3 AP) was K 4 [Cu(C 2 H 4 -O 5 P) 2 (H 2 O)]Á6H 2 O (Afonin et al, 1998), in which the Cu 2+ ion is ®ve-coordinated by four O atoms of two bidentate chelating phosphonoacetate trianions and the O atom of the water molecule.…”

In the crystal structure of the title compond, alternatively called poly[calcium(II)-di-mu-carboxymethylphosphonato], [Ca(C(2)H(4)O(5)P)(2)](n) or [Ca(H(2)AP)(2)](n), one of the phosphonate O atoms of the phosphonocarboxylate monoanion lies nearly antiperiplanar (ap) to the carboxylic acid C atom. The phosphonate P atom is located -sc and +ac relative to the carboxylic acid O atoms. The overall structure has a layered architecture. The Ca(2+) cations lie on a twofold axis and are bridged by the phosphonate O atoms to form chains along the c axis, giving layers parallel to (100). There are medium-strength O-H...O and C-H...O hydrogen-bonding interactions stabilizing the layers, and O-H...O hydrogen bonds connect adjacent layers.

“…The continuing research in the chemistry of metal-organophosphonates (1)(2)(3) can be attributed to the diversity of interesting structures associated with this class of material, as well as to their practical applications, for example, as catalysts (4) and ion exchangers (5,6). A comparison of a variety of these layered structure types is contained in Table 1.…”
