Tetrachlorobis diethyl sulfide platinum IV

Bis(4-imino-2-pentanonato)nickel(II), synthesis 60 Tris(ethylenediamine)platinum(IV) chloride, synthesis 62 cis-Dichloro(ethylenediamine)platinum(Il), synthesis 63 cis- and [Pg.14]

As prepared above, cfs-tetrachlorobis(diethyl sulfide)-platinum(IV) is bright yellow, whereas the trans isomer is lemon-yellow. If the cis isomer is heated on a melting-point block well below its melting point, it isomerizes and does not melt until the temperature reaches 195 to 198°. However, if the substance is placed on a melting-point block which has been preheated to 133°, it melts, solidifies almost immediately, and remelts at 201°, the melting point of the trans isomer. The trans isomer also sinters at about 10° below its melting point.
