In the last line of the title, the compound should appear as given above. In the abstract, 2a and 2b should be written as [MzL6(cc-CHWC18H2zO)]+BF4-, where CHE CCl8HZ20 represents 17a-ethynyl-3-hydroxyestradiol. 2a’ and 2b’ should be [MzL&-CHWClJ4,0)]+BF4-, where CH=CC1J4,0 = 17a-ethynyl-3-methoxyestradiol. In the Introduction, l a and lb should read [M&(p-RC= CC18HaOz)]. la’ and lb’ should read [M,L6(pRC= CC1&,Oz)]. The formula in the fourth and fifth lines of the Introduction should read [MzL8(p-RC=CC- (OH)RIR,)]. In the Experimental Section, the compounds la, la’, lb’, and 2b’ should be written with the correct formulas mentioned above. In the Results and in the Discussion, 2b’ should be [MozCpz(CO),(p-CH= CC19Hz40)]+BF,- and the molecular structure of this compound should be [ M O ~ C ~ ~ ( C O ) ~ ( C ~ ~ H ~ ~ O ) ] + .
