In the eighth O site, O is bonded in a distorted bent 150 degrees geometry to two equivalent Rb, one Ti, and one P atom. In the ninth O site, O is bonded in a 2-coordinate geometry to one Rb, one Ti, and one P atom. In the tenth O site, O is bonded in a distorted bent 150 degrees geometry to one Rb, one Ti, and one P atom. In the eleventh O site, O is bonded in a bent 150 degrees geometry to two Ti atoms. In the twelfth O site, O is bonded in a 2-coordinate geometry to one Rb, one Ti, and one P atom. In the thirteenth O site, O is bonded in a distorted bent 150 degrees geometry to one Rb, one Ti, and one P atom. In the fourteenth O site, O is bonded in a 2-coordinate geometry to one Rb, one Ti, and one P atom. In the fifteenth O site, O is bonded in a bent 150 degrees geometry to one Rb, one Ti, and one P atom. In the sixteenth O site, O is bonded in a distorted bent 150 degrees geometry to two equivalent Rb, one Ti, and one P atom.
