The standard molar enthalpy of sublimation of Fe(c-C5H5)2,bis(h-cyclopentadienyl)iron(II), ferrocene, has been experimentally determined by the Knudsen-effusion method using a quartz-crystal microbalance. The results from two series of experiments were found to be DsubH°m(298.15 K)=(74.3420.41) kJ•m
