A Sodalite-Type Porous Metal−Organic Framework with Polyoxometalate Templates: Adsorption and Decomposition of Dimethyl Methylphosphonate

A sodalite-type porous metal-organic framework with polyoxometalate templates, H(3)[(Cu(4)Cl)(3)(BTC)(8)](2)[PW(12)O(40)]·(C(4)H(12)N)(6)·3H(2)O (NENU-11; BTC = 1,3,5-benzenetricarboxylate), was obtained by a hydrothermal reaction. As a reasonable candidate for eliminating nerve gas, NENU-11 displays good adsorption behavior for dimethyl methylphosphonate (15.5 molecules per formula unit). In virtue of the catalytic activity of polyoxometalate guests, this nerve gas mimic could be facilely decomposed by a hydrolysis reaction.

A 9-connected metal–organic framework with gas adsorption properties

A 9-connected, trinuclear cluster-based microporous metal–organic framework, Ni3(OH)(Ina)3(BDC)1.5 (Ina = isonicotinate and BDC = 1,4-benzenedicarboxylate) (1), was synthesized and characterized. The structure is constructed from a 3D channel and two kinds of cages (tetrahedron and triangular pyramid cages). Compound 1 is microporous with a BET surface area of 1255 m2 g−1. It has been observed that the amount of adsorbed benzene (22.60%) is much higher than that of cyclohexane (1.40%), showing its potential to separate benzene and cyclohexane.

Synthesis, crystal structure, and fluorescence of a 2-D coordination polymer

A 2-D coordination polymer with mixed ligands, [Zn2(BDC)(4,4′-bipy) (HCOO)2] (1) (BDC, 1,4-benzenedicarboxylate; 4,4′-bipy, 4,4′-bipyridine), has been synthesized by solvothermal reaction. Compound 1 provides the first coordination polymer structure constructed by bridging BDC, 4,4′-bipy, and formate. Both BDC and 4,4′-bipy link zincs alternatively, resulting in a zigzag coordination chain; adjacent chains are further linked by formates to form an infinite extended 2-D folding screen layer. The synthesis mechanism and fluorescence property are discussed.
