摘要: Building pyramids: The first P-C cluster, namely, the novel nido species 2, is readily prepared from 1 (=CtBu), which also an excellent precursor for selective synthesis of anion 3. DFT calculations show that there a switch in global minimum, on introduction three P atoms (CH) into [C5H5]+ ion, cyclic-unsaturated to saturated cage species, such as 2.
