The crystal structure of the original natural gugiaite, Ca2BeSi2O7, from the skarn rocks in the Gugia alkaline complex, Liaoning Province, China, is determined from CCD data in space group P4¯21 m, a = 7.4330(10), c = 4.9970(10)A°, V = 276.08(8) A°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 distortions of SiO4 tetrahedron than those in synthetic one.
