(CH3)3PbOOCH3 is available from Alfa / Aesar cat# 57136, 1g for US $94.50. Alfa
is located in Massachusetts and can be called at (800) 343-0660. If calling from
outside the US, I think you cannot dial a toll free number so try: (508)
521-6300.  Alfa and STREAM CHEMICALS (as pointed out) are  very good sources for
all of a crystallographers heavy atom needs .
