摘要：

A new s-Ca19Cu2(PO4)(14) monophosphate with the whitiockite-like structure was synthesized and its structure was determined by the Rietveld analysis (R-wp = 6.15%, R-p = 4.66%, R-1-3.44%, R-F = 2.08% for 758 reflections). The crystal symmetry is trigonal (R3c space group, Z = 3) and the hexagonal unit cell parameters are a = 10.3638(1) Angstrom, c = 37.219(2) Angstrom, and V = 3462(2) Angstrom(3) The copper atom is octahedrally coordinated.
