Correlation between the stereochemistry and optical activity of chiral dimolybdenum tetracarboxylates and related compounds
1990
Sector rules for chiral dimolybdenum tetracarboxylates and related compounds were derived using the “one-electron model” of optical activity. The correlation between the sign of the Cotton effect (CE) of the δ→δ* transition and the stereochemistry of this type of binuclear clusters is expressed as a rule of 16 in which the positive sign of the EC corresponds to the negative sign of the pseudoscalar function xyz(x2-y2) of the cluster atoms. A negative sign of the CE was predicted for the δ→δ* transition in cis-(L-isoleucine)2(NCS)4Mo2.
