Topologically, the polymer 1 exhibits a two-dimensional (2D) Cd-HBTC network with (44) topology, which is a sql structure; the polymer 2 possesses a three-dimensional (3D) porous Cd-BTC framework with (4·62)2(42·610·83) topology, which is a contorted rutile structure; polymer 3 exhibits a 3D open Cd-BTC architecture with (62·82·102)2(62·84)(63)4 topology; polymer 4 is a 3D porous Cd-BTC network with new (4·62)2(42·64·86·103)(6·82)2(62·84)(62·84)2(62·8)2 topology; similar to 1, polymer 5 is a 2D Zn-BTC framework with (4·82) topology; interestingly, polymer 6 possesses a 3D porous Cd-BTC architecture with the same topology as 2; polymer 7 shows a 3D open Cd-BTC framework with (63)(65·10) topology. In addition to the structures of polymers 1–7, their thermal stabilities, ion exchange properties, and nonbonding interaction energies, including H-bonding and van der Waals, have also been studied. Remarkably, those organic amine cations reside in the interlayer or channel space, playing important roles such as templating, space-filling, and charge-balancing agents.

A Series of Three-Dimensional Lanthanide Coordination Compounds with the Rutile Topology

A series of three-dimensional lanthanide coordination compounds with rutile topology, M(CTC)(DMF)(H2O)·(DMF)(H2O) (M = Tb (1), Dy (2), Ho (3), Er (4), and Tm (5), CTC = cis,cis-1,3,5-cyclohexanetricarboxylic acid, DMF = N,N′-dimethylformamide), have been synthesized under mild conditions. They are isomorphous and crystallize in monoclinic symmetry with space group P21/n. The structure can be considered to be built up from metallic 6-connected and organic 3-connected building units with vertex symbol (4·4·4·4·64·64). These lanthanide coordination compounds possess 10.4 × 10.1 Å2 channels along the [100] direction, and 7.7 × 7.7 Å2 channels along the [011] and [01̅1] direction, respectively. The fluorescent, water, and methanol adsorption properties of these compounds are studied, and the results reveal that they could be potentially utilized as multifunctional materials

Structure, Luminescence, and Adsorption Properties of Two Chiral Microporous Metal−Organic Frameworks

Two 3D chiral multifunctional microporous MOFs, Zn3(BTC)2(DMF)3(H2O)·(DMF)(H2O) (1) and Cd4(BTC)3(DMF)2(H2O)2·6(H2O) (2) (H3BTC = 1,3,5-benzenetricarboxylic acid and DMF = N,N‘-dimethylformamide), have been synthesized in the presence of organic bases tributylamine (TBA) and triethylamine (TEA), respectively. 1 (C30H38N4O18Zn3) crystallizes in the tetragonal P41212 space group (a = 13.6929(19) Å, c = 50.664(10) Å, V = 9499(3) Å3, and Z = 8). 2 (C33H39N2O28Cd4) crystallizes in the tetragonal P4322 space group (a = 10.3503(4) Å, c = 52.557(3) Å, V = 5630.4(4) Å3, and Z = 4). X-ray crystallography reveals that 1 consists of a 3D open framework with the (63)4(62·82·102)(6·482)2 topology, but 2 exhibits a 3D open network with the (42·5)2(4·45·106·87·482) topology. The solid-state excitation−emission spectra show that the strongest excitation peaks for 1 and 2 are at 341 and 319 nm, and their emission spectra mainly show strong peaks at 410 and 405 nm, respectively. The amounts adsorbed of 1 (2) are 169 mg/g (126 mg/g) for H2O, 137 mg/g (102 mg/g) for C2H5OH, and 133 mg/g (99 mg/g) for CH3OH, which are equivalent to the adsorption of about 62 (34) H2O, 20 (11) C2H5OH, and 28 (16) CH3OH per unit cell, respectively
