This mineral was discovered in Zapachitsa (Zapacica) copper deposit, Svoge, Sofia Oblast, Bulgaria in 1960, by Bulgarian mineralogist Jordanka Minčeva-Stefanova. She named it after Strashimir Dimitrov (1892–1960), Professor in Mineralogy and Petrography at Sofia University "St Kliment Ohridski", Bulgaria. The International Mineralogical Association approved it as a new mineral in 1968.
