mineral

mineral - mineral - Carbonates: The carbonate minerals contain the anionic complex (CO3)2–, which is triangular in its coordination—i.e., with a carbon atom at the centre and an oxygen atom at each of the corners of an equilateral triangle. These anionic groups are strongly bonded individual units and do not share oxygen atoms with one another.
