摘要：

K2CuP2O7 crystallizes in the orthorhombic space group Pbnm, a=9.509(4), b=14.389(6), c=5.276(2) Angstrom, D-calc=2.904 g cm(-3), Z=4, R/R(W)=4.6/5.9% for 1172 observed reflections. The solid state structure shows square pyramidal coordination for Cu2+ (Cu2+-O, average 2.043(5) Angstrom) and sevenfold or ninefold coordination for the two potassium atoms (K-O, average 2.748(3) and 2.966(5) Angstrom respectively). Comparisons may be drawn with the crystal structures of alpha-Sr2P2O7, alpha-Ca2P2O7 and the low temperature form of Na2CuP2O7.
