Abstract

Four new diphosphate compounds of the type A¹¹P₂O₇ have been synthesized and characterized by single-crystal X-ray diffraction. While all four have similar unit cell dimensions, BaPbP₂O₇ is isotypical with α-Sr₂P₂O₇ (space group Pmnb), whereas PbCoP₂O₇, PbMnP₂O₇ and PbCuP₂O₇ are similar to α-Ca₂P₂O₇ (space group P2₁/n). P₂O₇^4- groups show average O-P... P-O angles which range from 0.0° to 49.56° and are intermediate between the 0.0° expected of dichromate-type structures and the 60.0° expected of thorveities. The magnitude of the O-P.. P-O angle is correlated with the ionic radius of the smaller cation in each compound. Furthermore, the change in space group for BaPbP₂O₇ may be seen to be a consequence of the ionic radii of the B atom. Metal coordination numbers in the four complexes range from 5 to 9.
