EXPONENTIAL DECAY OF A CHARGE TRANSFER INDUCED BY COORDINATION IN ORGANOMETALLIC COMPLEXES

In the series of organometallic complexes N3P2(X)5P-SPACER-MLn X= Cl and OR, MLn= organometallic fragment , the delta31 P-NMR coordination chemical shift parameter correlates with the length of the spacer, decaying exponentially with the length of it. The bridging spacers behave like a "molecul...
