Abstract
The crystal structure of the original natural gugiaite, Ca2BeSi2O7, from th e skarn rocks in the Gugia alkaline complex, Liaoning Province, China, is d etermined from CCD data in space group P (4) over bar2(1)m, n = 7.4330(10), c = 4.9970(10) Angstrom, V = 276.08(8) Angstrom (3), Z = 2. The structure is basically consistent with that of the synthetic one, although there are longer Be-O distances, smaller distortions of BeO4 tetrahedron and larger d istortions of SiO4 tetrahedron than those in synthetic one.
