• We report a 1:1 complex of Lanthanide-substituted oxo-nitrosyl polymolybdate.
• The tittle compound was constructed by a one-pot self-assembly process.
• It would be applied in post-modification or self-assembling procedures.
• Diverse structures may be obtained by using it as the building-block.
A 1:1 complex of Lanthanide-substituted Lindqvist-type oxo-nitrosyl polymolybdate [NBu4][La(CH3OH)2(DCU)NO3{Mo5O13(OMe)4(NO)}]·CH3OH (1) has been successfully synthesized by a one-pot self-assembly process of hydroxylamine hydrochloride with octamolybdate, DCC and La(NO3)3 in methanol under mild reaction conditions. The structure is determined by X-ray crystallography. It is notable that the compound is a Lindqvist-type POM with a capped lanthanum ion which is nine coordinated in a distorted square antiprism geometry. Interestingly, NO3− as the precursor, as well as the hydrated product DCU of DCC, are both coordinated with Lanthanum ion. The structure has also been characterized by IR, UV–vis and photoluminescence analysis. Photoluminescence analysis reveals that compound 1 emits weak green light in CH3CN, with the maximum emission at 530 nm.
