• The reactions of (C<SUB>6</SUB>H<SUB>5</SUB>)<SUB>3</SUB>P=CH<SUB>2</SUB> (<B>L</B>) with BeCl<SUB>2</SUB> or MgCl<SUB>2</SUB> in the mole ratio of 2 : 1 or 4 : 1 yield new dimeric compounds of di-μ-chloro-bis[(methylenetriphenylphosphorane)metal] dichloride, (<U>Remark: Graphics omitted.</U>) (M: Be and Mg). The configuration of these metals is trigonal. The reactions of <B>L</B> with AlCl<SUB>3</SUB>, GaCl<SUB>3</SUB> or InCl<SUB>3</SUB> in the mole ratio of 2 : 1 yield new compounds of di-μ-chloro-bis[bis(methylenetriphenylphosphorane)metal] tetrachloride, (<U>Remark: Graphics omitted.</U>) (M: Al, Ga, and In). The reactions of <B>L</B> with AlCl<SUB>3</SUB> or GaCl<SUB>3</SUB> in the mole ratio of 3 : 1 or 5 : 1 yield new compounds of μ-chloro-bis[tris(methylenetriphenylphosphorane)metal] pentachloride, [{(C<SUB>6</SUB>H<SUB>5</SUB>)<SUB>3</SUB>PCH<SUB>2</SUB>}<SUB>3</SUB>M–Cl–M{CH<SUB>2</SUB>P(C<SUB>6</SUB>H<SUB>5</SUB>)<SUB>3</SUB>}<SUB>3</SUB>]Cl<SUB>5</SUB> (M: Al, Ga). These dimers, bridged by chloride anions, are thermally stable.
