Influence of the molecular configuration on second-order nonlinear opticalproperties of coordination compounds

The relationships between structure and nonlinear optical (NLO) properties of coordination compounds in terms of influence of molecular configuration on linear and NLO properties are reviewed. The molecular configurations inv olved are square pyramidal, tetrahedral, square planar, octahedral, sandwic h and linear. Based on the experimental results, empirical rules of these r elationships have been proposed, which may help the design of new NLO mater ials from organometallic and coordination compounds.
