We present the preparation of the electron-doped quasi-two dimensional quantum antiferromagnet (CuCl)LaNb 2 O 7 by two step-wise topochemical reactions. The first step involves a reductive fluorination of the insulating layered perovskite RbLaNb 2 O 7 using polytetrafluoroethylene that allows electric conduction in the perovskite blocks. The product RbLaNb 2 O 6 F was then ion-exchanged with copper dichloride to yield (CuCl)LaNb 2 O 6 F. The synchrotron x-ray diffraction study indicates that
