This paper describes a generalized and extended treatment of the preceding papers in which the maximum overlap method was employed but the results were limited by the. condition that the number of Iigands surrounding the central atom should be two, that is, k = 2 in molecule MLko Based on the special assumption. that the angles < LpMLq = a between any two M-Lj bonds in molecule MLk are equal, many general formula s related to the diagonal matrix D (Jo), unitary matrix U", overlap matrix Sl and the bond strength F a...
