摘要：

A suspension of a yellow polycrystalline compound [PPh4](3)[(PMo12O40)-O-VI] 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)[(PMoMo11O40)-Mo-V-O-VI].3CH(3)(C6H5)NCHO (1). Compounds [PPh4](3)[(PMo12O40)-O-VI].1.75 CH3(C6H5)NCHO (2) and [PPh4](3)[(PMo12O40)-O-VI].2CH(3)(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.
