Formula:
MXY


Members of the Matlockite Group are layer structures based on metal-oxygen or metal-fluorine layers in which the anions are in quadratic packing with the metal cations (Pb, Ca, Bi) fitting into the interstices between the anions, half on each side of the layer. These layers are separated by double layers of Cl or (Cl,OH), each in quadratic packing which coordinate the metal anions of the first-described layers (Palache, C., Berman, H., & Frondel, C. (1951), The System of Mineralogy of James Dwight Dana and Edward Salisbury Dana, Yale University 1837-1892, Volume II: 59).
