摘要：

Mercury(II) diphosphate, Hg2P2O7, belongs to the M2X2O7 family of compounds with dichromate-type crystal structures and is isotypic with Cd2P2O7. The structure consists of alternating layers built from P2O7 groups and highly distorted HgO6 polyhedra with bond distances in the ranges 2.120(6) less than or equal to d(Hg1O(6)) less than or equal to 2.793 (7) Angstrom and 2.208 (6) less than or equal to d(Hg2O(6)) less than or equal to 2.509(6) Angstrom. The diphosphate anion has a P-O-P bridging angle of 133.4(4)degrees. The average P-O bond length is 1.604 Angstrom for bridging and 1.524 Angstrom for terminal bonds. [Hg1(2)O(10)] and [Hg2(2)O(10)] form chains running along [110] through edge-sharing dimers. These chains link to form layers parallel to ((1) over bar 10) via common vertices.
