Middlebackite is an organic mineral with the formula Cu2C2O4(OH)2. It was first discovered within a boulder from the Iron Monarch quarry in South Australia in June 1990.[1] Peter Elliott from the University of Adelaide, Australia, identified the structure of the mineral 25 years later. He determined its crystal structure through single-crystal X-ray diffraction using synchrotron radiation. Elliot named the mineral for the Middleback Range where it originated.[2] In 2018 middlebackite was found in Val di Fiemme, Italy, during researches that brought to the discovery of a new mineral named fiemmeite.[3]
