Abstract:
A suspension of a yellow polycrystalline compound [PPh4]3[PMoVI12O40] in N-methylformanilide (NMF) (in which it is not soluble), on irradiation with sunlight, initiates dissolution via its reduction followed by its crystallization leading to the isolation of single crystals of compound [PPh4]4[PMoVMoVI11O40]·3CH3(C6H5)NCHO (1). Compounds [PPh4]3[PMoVI12O40]·1.75 CH3(C6H5)NCHO (2) and [PPh4]3[PMoVI12O40]·2CH3(C6H5)NCHO (3), each containing an oxidized Keggin anion, are obtained at two different temperatures when the corresponding mother liquor is kept in the dark.
