[(C 5 HR 4 )PCl 2 ] ( 1a ), [(C 5 HR 4 )PBr 2 ] ( 1 b ), [(C 5 HR 4 )AsCl 2 ] ( 2 ), and [(C 5 HR 4 )SbCl 2 ] ( 3 ), have been obtained from the corresponding pnicogen trihalides and sodium tetraisopropylcyclopentadienide (R = CHMe 2 ). The molecular structures of 1, 2 , and 3 as well as the related structure of [(C 5 HR 4 )BiCl 2 ] ( 4 ) display increasing π character of hetero atom to cyclopentadienyl bonding with increasing metallic character of the hetero atom.
