Abstract

The optimum empirical formula and a model for the ordered crystalline motif for the high-

T_{c}

(155 K), fluoride-substituted ceramic, Y

{Ba}_{2}

{Cu}_{3}

O_{6}

F_{2}

are deduced based on simple structural considerations. The average Cu-atom oxidation state (2.33) is predicted to be the same as in the oxygenated meterial (

T_{c} \sim 95

K), Y

{Ba}_{2}

{Cu}_{3}

O_{7}
