Abstract
The melting points, vapour pressures and heats of sublimation of the complexes of Ga, In, Y, La, Gd, Fe, Zn, Pb and Li with 2,2,6,6-tetramethyl-3,5-heptanedione are reported for the temperature range below the melting point of 40‡ to 250‡C and pressures from 10 to 10−2 torr. The measurements were made with an easily constructed Knudsen effusion cell in conjunction with a Mettler thermobalance.
