Abstract: Chemical bond parameters in RBa2Cu4O8(R=Dy, Ho, Er, Tm, Yb) and Y2Ba4Cu7O14.3 were calculated by using complex chemical bond theory. The results indicated that the bond covalency in CuOchain was larger than that in CuO2 plane. For metal atoms, the bond covalency of five coordinated case was larger than that of six coordinated case.

Key words: Chemical bond parameters, RBa2Cu4O8, Y2Ba4Cu7O14.3
