O-17 NMR measurements on (Tl,PB)Sr2Ca2Cu3O9-delta (T-c=124K) show that the Knight shift of the outer two Cu-O planes (with pyramidal coordination for copper) has a very different behavior to that of the inner plane (with square coordination for copper). The former has a larger magnitude and a weaker temperature dependence in the normal state, whereas the latter is smaller but has a stronger temperature dependence, implying a nonhomogeneous charge distribution and a weak interaction among the Cu-O layers. The results are compared with those for (Bi,Pb)(2)Sr2Ca2Cu3O10-delta (T-c=107K) and Tl2Ba2Ca2Cu3O(10-delta) (T-c=l25K).
