Zr₆O₈ core cluster with formula unit [Zr₆O₄(OH)₄(OH₂)₈(CH₃COO)₄(SO₄)₄]·nH₂O obtained under mild conditions.

ABSTRACT: During attempts to synthesize zirconium-based MOFs, we have obtained a new crystal structure of the cluster with Zr₆O₈ core and formula unit [Zr₆O₄(OH)₄(OH₂)₈(CH₃COO)₄(SO₄)₄]·nH₂O. Unlike other systems, mild conditions were employed in this case; no strong acids or hydrothermal conditions were required. The molecular assembly in the crystal is characterized by strong O-H⋯O hydrogen bonds connecting neighboring molecules, allowing the formation of a three-dimensional maze of tunnels with H₂O molecules stabilizing the framework. Noteworthy, at 100 °C, the strong Zr₆O₈ core and the O-H⋯O hydrogen bonds help form a system wh
