[O][Mn][=O].[O][Mn][=O].[Mn]"}, {"from": "gpt", "value": "The molecule is an oxide of manganese where the manganese is present in both the 2+ and 3+ oxidation states. It is found in nature as the mineral hausmannite and is used as a starting material in the production of soft ferrites and lithium manganese oxide, as well as in lithium batteries. Manganese is a naturally occurring metal with the symbol Mn and the atomic number 25. It does not occur naturally in its pure form, but is found in many types of rocks in combination with other substances such as oxygen, sulfur, or chlorine. Manganese occurs naturally in most foods and small amounts are needed to stay healthy, as manganese ions act as cofactors for a number of enzymes. (L228, L229, L238)"}]
