Abstract

A new series of ionic crystals, KH₂[Cr₃O(OOCCH ₃)₆-(H₂O)₃][α-SiMo ₁₂O₄₀] ·11H₂O (1), KH ₂[Cr₃O(OOCCH₃)₆(H₂O) ₃]-[α-SiW₁₂O₄₀]·11H₂O (2), K₂[Cr₃O(OOCCH₃)₆ (H ₂O)₃][α-PW¹²O₄₀]· ₁₇H₂O (3), Na[Cr₃O(OOCCH₃) ₆(H₂O)₃]₂[α-PMo ₁₂O₄₀] ·11H₂O (4), H₅[Cr ₃O(OOCCH₃)₆(H₂O)₃] [α-P₂Mo₁₈O₆₂] ·10H₂O (5) based on a polyoxometalate building block with a macrocation, have been synthesized in aqueous solution and structurally characterized by single-crystal X-ray diffraction, IR spectra, elemental analysis, thermogravimetric analysis (TGA). The polyanions and macrocations stacked alternately through hydrogen bonds as well as electrostatic interactions to constitute a novel porous microstructure. In the crystal structures of 1, 2, and 3, oppositely charged cluster ions stacked alternately to form one-dimensional channels. Compound 4 exhibits an unique structure that six macrocation pillars packed along the a-axis to form a straight ID channel, in which accommodates a polyoxometalate pillar. In compound 5, six α-Dawson-type polyoxometalate pillars stacked on top of each other along the a-axis to form a straight ID channel, which houses a macrocation pillar. The magnetic investigation on compounds 1 and 5 shows a typical antiferromagnetic interaction of the macrocation [Cr ₃O(OOCCH₃)₆(H₂O)₃] ⁺, almost independent from the presence of polyoxometalate anions.
