A new flexible tritopic ligand, 1,3,5-tri(4-cyanophenoxy)benzene (1), was synthesised by the reaction of phloroglucinol and para-fluorobenzonitrile. Compound 1 crystallises in the non-centrosymmetric space group Pna21. The reaction of ligand 1 with AgBF4 in the presence of different aromatic guest molecules was found to result in coordination polymers, namely, {[Ag3(1)2(BF4)3(H2O)2]·2C7H8·2CH2Cl2}n (2), {[Ag3(1)2(BF4)3(H2O)2]·2C6H6·2CH2Cl2}n (3). The crystal structures of 2 and 3 reveal that ligand 1 is linked by AgI ions into three-dimensional networks containing channels that are occupied by dichloromethane and aromatic guest molecules. The luminescent properties of crystalline 1 and 3 differ significantly.

Structures And Properties

Two new Ce(III) coordination polymers formulated as Ce(bpdc)(Hbpdc)(DMF)2 (1) and [Ce2(bpdc)3(DMF)2(H2O)4]·2DMF (2) (H2bpdc = 2,2'-bipyridine-4,4'-dicarboxylic acid, DMF = N,N-Dimethyl formamide) have been synthesized under solvothermal condition and characterized by single-crystal X-ray diffraction. Compound 1 crystallizes in monoclinic, space group C2/c with a = 2.2520(2), b = 1.17787(12), c = 1.16128(11) nm, α = 90, β = 95.5600(10), γ = 90°, V = 3.0658(5) nm3, Z = 4, Mr = 771.70, Dc = 1.672×10-9 g/cm3. Compound 2 crystallizes in triclinic, space group Pwith a = 1.00610(10), b = 1.17219(11), c = 1.36891(14) nm, α = 66.9340(10), β = 87.182(2), γ = 76.2570(10) °, V = 1.4411(2) nm3, Z = 1, Mr = 1371.25, Dc = 1.580×10-9 g/cm3. Both compounds exhibit 3D Ce(III)–organic frameworks. Furthermore, thermal stability and luminescent properties were also investigated. CCDC:(1)913670, (2)909563.

Two ZnII-based coordination polymers (CPs) were synthesized by the hydrothermal method, using Zn(NO3)2·6H2O and furan-2,5-dicarboxylic acid (FDCA) in dimethylformamide (DMF) solvent, at 95 °C. Poly[tetrakis(dimethylazanium) [tetrakis(μ2-furan-2,5-dicarboxylato-κ2 O 2:O 5)dizinc(II)]], {(C2H8N)4[Zn2(C6H2O5)4]} n or {[DMA]4[ZnII 2(FDC)4]} n (DMA = dimethylazanium and FDC = furan-2,5-dicarboxylate), (1), was obtained with a 1:1 molar ratio of ZnII and FDCA. It crystallized in the monoclinic space group C2/c. Coordinated by ZnII ions, FDC2− ligands form 21 double-stranded helices propagating along the b axis. The helices are interconnected and extend laterally in the a direction, forming a two-dimensional (2D) sheet-like network. The 2D sheets are stacked along the c direction without interconnections. DMA cations are cocrystallized in (1) and are hydrogen bonded with carboxylate O atoms of the FDC2− ligands. The hydrogen-bonding pattern consists of R 2 2(4) and R 2 2(10) motifs alternating in a chain. Poly[bis(dimethylazanium) [bis(μ4-furan-2,5-dicarboxylato-κO 2:κO 2′:κO 5:κO 5)bis(μ3-furan-2,5-dicarboxylato-κO 2:κO 2′:κO 5)dizinc(II)] dimethylformamide 3.08-solvate], {(C2H8N)2[Zn2(C6H2O5)4]·3.08C3H7NO} n or {[DMA]2[ZnII 3(FDC)4]·3.08DMF} n , (2), was obtained with a 1:2 molar ratio of ZnII and FDCA. It crystallized in the monoclinic space group P21/c, forming a three-dimensional network. The pores are filled with DMA cations and DMF solvent molecules.
