Synthesis and structure of alkali-metal triorganozincates

The potassium and sodium trialkylzincates KZn(CH2CMe3)3 (1), NaZn(CH2CMe3)3 (2), and KZn-(CH2SiMe3)3 (3) were isolated from reactions between the alkali metal and R2Zn in benzene. The compounds all metalate benzene, and in fact KZn(CH2SiMe3)2Ph (4) was isolated during the synthesis of 3. The crystal structures of 1-4 show all four complexes to consist of ZnR3- and K+ or Na+ ions. Potassium ions in 4 join the ZnR3- ions into a polymeric lattice, while 1-3 crystallize as discrete dimers. The K+ ions in 1 are solvated with weakly coordinated benzene, while the Na+ ions in 2 and the K+ ions in 3 have weak contacts outside the dimeric unit. Only the Na complex 2 sublimes under vacuum.
