The crystal structure of [{OVV(salen)}2(μ-F)][VIVO(salen)][BF4]·(CH2Cl2)x revealed a hollow cavity with a diameter of 5.3 Å that penetrates through the crystal, and a remarkable cyclic chain of the [VO(salen)] unit, a motif that has never been fashioned from oxometal building blocks. These features endow the crystal with a molecular sievelike property for the rapid, reversible, and size-selective absorption of guest CH2Cl2 molecules.
