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). P2O74- 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.
