The incorporation of the intensely coloured charge transfer species MnO43- has been investigated for NaCaVO4. The series of compounds NaCaV1-xMnxO4 (where x = 0, 0.02, 0.04, 0.06, 0.08, 0.1) has been successfully prepared and results in the formation of blue/green coloured powders. A structural characterisation of the materials has been performed and the results are presented. The series is seen to adopt an orthorhombic structure in the space group Cmcm (No.63). On increasing manganese content an overall reduction of the cell volume was observed and the limit of substitution occurs at x 0.08.
