Along with the abundant pyromorphite, relatively frequent coronadite was found in the Řimbaba mine in Bohutín near Příbram (Czech Republic). Coronadite forms up to 5 mm thick black matt and greasy coatings and cavity fillings. The unit cell parameters of coronadite, refined from the powder X-ray diffraction data, are a 9.943(17), b 2.876(8), c 9.820(11) Å, β 90.4(5)° and V 280.8(9) Å3 (space group I2/m). Chemical analyses correspond to the empirical formula Pb1.53Sb0.07Zn0.02(Mn4+5.62Mn3+2.06)O16.
