The Square Pyramidal Configuration in a Five-Co-ordinate Nitrosyl Complex
MOST molecules which have a five-co-ordinated central atom, and the structures of which have been accurately determined, have the shape of a trigonal bipyramid; for example, PF 5 , (CH 3 )SbBr 2 , Fe(CO) 5 . Nevertheless, in their study of valency theory, Daudel and Bucher 1 predicted that a five-co...
