Abstract:
An unprecedented bird‐nest high‐nuclear molybdenum(V) cobalto‐phosphate nanosized wheel modified by imidazole (im) and pyridine (py), {[H 55 (Mo 24 O 48 )(Co 4 O) 2 Co 16 (PO 4 ) 42 (py) 6 (EtOH) 2 (H 2 O) 11 ]‐ @[(Him) 2 (Hpy)]}(N‐Et‐py)(H 2 PO 4 )(py) 7 (EtOH)⋅12 H 2 O ( 1 ), has been successfully synthesized by self‐assembly. The anionic huge wheel consists of two rare {Co 4 O} squares, four {Co 4 } tetramers, four {Mo 4 } tetramers and four {Mo 2 } dimers, linked by bridging oxygen atoms and [PO 4 ] groups and encloses two imidazolium cations and a protonated pyridium for charge balance. Surprisingly, 1 represents the first twisted wheel‐shaped cluster with a record high‐nuclear molybdenum(V) cobalto‐phosphate. The delocalized electron effects of the cluster are enhanced with the help of coordinated py ligands, which endows 1 with an excellent third‐order nonlinear optical (NLO) response. Additionally, 1 also shows a better photocatalytic water oxidation activity than Co(NO 3 ) 2 with the O 2 production of 205 μmol during 6 h in the absence of the [Ru(bpy) 3 ] 2+ photosensitizer.
