Abstract

X-ray powder diffraction data, unit-cell parameters and space group for a rare natural organic mineral refikite, C20H32O2, abiet-13(15)-en-18-oic acid, are reported [a = 22.55(2) Å, b = 10.469(6) Å, c = 7.930(9) Å, unit-cell volume V = 1871.82 Å3, Z = 4 and space group P21212]. All measured lines were indexed and are consistent with the P21212 space group. No detectable impurities were observed.
