摘要：

The reactions of [(thf)(4)Ca(PPh2)(2)] with the iron carbonyls Fe-2(CO)(9) and Fe-3(CO)(12) in THF yield mixtures of iron carbonyl-containing phosphanides which transform upon prolonged heating into [(thf)(4)Ca{Fe-2(CO)6(mu-CO)(mu-PPh2)} (2)] (1) with a chemical shift of delta(P-31) = 127.9 ppm. The distorted octahedrally coordinated calcium atom binds to four THF molecules (av. Ca-O 234.0 pm) and the bridging carbonyl ligand of the complex anions {Fe-2(CO)(6)(mu-CO)(mu-PPh2)}(-)[Ca-O 229.8(4), Fe-Fe 257.9(2) pm].
