A new chlorooxocuprate, Ca{sub 3}Cu{sub 2}O{sub 4}Cl{sub 2}, is prepared and the crystal structure is determined by Rietveld analysis of X-ray powder diffraction data. This compound crystallizes in tetragonal symmetry with a space group of I4/mmm and with lattice parameters of a = 3.863 {angstrom} and c = 21.364 {angstrom}. The crystal structure is similar to that of Sr{sub 2}Ti{sub 3}O{sub 7} except for oxygen vacancies located between two-dimensional Cu-O planes, and for chloride anions occupying apical sites of doubled copper octahedra. Interatomic distances of the compounds are comparable to those of Ca{sub 2}CuO{sub 2}Cl{sub 2} with a K{sub 2}NiF{sub 4} structure.
