Abstract

An unprecedented bird-nest high-nuclear molybdenum(V) cobalto-phosphate nanosized wheel modified by imidazole (im) and pyridine (py), {[H₅₅(Mo₂₄O₄₈)(Co₄O)₂Co₁₆(PO₄)₄₂(py)₆(EtOH)₂(H₂O)₁₁]- @[(Him)₂(Hpy)]}(N-Et-py)(H₂PO₄)(py)₇(EtOH)⋅12 H₂O (1), has been successfully synthesized by self-assembly. The anionic huge wheel consists of two rare {Co₄O} squares, four {Co₄} tetramers, four {Mo₄} tetramers and four {Mo₂} dimers, linked by bridging oxygen atoms and [PO₄] 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(NO₃)₂ with the O₂ production of 205 μmol during 6 h in the absence of the [Ru(bpy)₃]²⁺ photosensitizer.
