AbstractWe have investigated the crystal structure of the synthetic analogue of the mineral iwateite using powder diffraction and Raman spectroscopy. Na2BaMn(PO4)2 crystallizes in the space group P$‾{3}$m1 (No. 164) with cell parameters a = 5.37292(1) Å, and c = 7.09538(1) Å (Rwp = 5.7%, V = 177.38 Å3, Z = 1). The space group assignment is supported by the experimentally observed 11 Raman active modes which agree with the expected number of modes for the P$‾{3}$m1 symmetry.
