Abstract

The structures of Ti-oxo clusters were thought to be rigid given the high stability of Ti–O–Ti bonds. A Ti₃₂-oxo nanoring, Ti₃₂(μ₂-O)₈(μ₃-O)₈(L)₁₆(gly)₃₂(glyH)₁₆·12(glyH₂)·29(IPA) (L = 4-aminobenzoic acid, glyH₂ = ethylene glycol, IPA = isopropanol) (1), experiences an unexpected single-crystal-to-single-crystal desolvation process upon exposure to air, affording another new crystalline phase Ti₃₂-oxo cluster (1-Dry) with a shrunk ring size.
