摘要

The monomeric solvent-free compound CaR2 1 [R= C (SiMe3) 3] is obtained as colourless air-and moisture-sensitive crystals from the reaction between KR and CaI2; in the solid the C– Ca–C axis is bent with Ca–C 2.459 (9) Å and C–Ca–C 149.7 (6)°; reactions of 1 with ethers ROEt give RH, ethene and Ca (OEt) 2.
