Three unprecedent polycational templated cuprous thiocyanate networks: synthesis, structure, and properties

Inspired by the lack of supramolecular hybrids induced by the multivalent interactions, we conducted three integrations of trication or tetracation with thiocyanate via strict templated self-assembly. These compounds represent the first type of 2–3 dimensional multi-threading polypseudorotaxanes based on Cu6(SCN)6 macrocycles.

Syntheses, Structure, Photoluminescent, and Thermal Properties of a Novel Coordination Polymer [CuI(4-bpfob)(HCN)(DMF)]n With One-Dimensional Helical Chain

Solution reaction of CuI and the ligand 4-bpfob [4-bpfob = N,N′-(1,2-phenylene)diisonicotinamide] led to the formation of a novel coordination polymer [CuI(4-bpfob)(HCN)(DMF)]n that exhibited an unusual one-dimensional helical structure. The compound was characterized by X-ray crystallography, infrared spectroscopy, fluorescence spectrum, and thermal analyses. This compound crystallized in triclinic system, space group P–1, with cell parameters of a = 8.3343(17) Å, b = 11.242(2) Å, c = 12.596(3) Å, α = 99.61(3)°, β = 93.11(3)°, and γ = 92.97(3)°.

Three novel hybrid complexes, namely{(DMB)[Cu2(SCN)4]}n (1), {(DMB)[Cu(SCN)4]} (2), and {(DMB)[Ag2(SCN)4]}n (3), have been synthesized via the self-assembly in DMF–methanol system based on multidentate ligand DMB, {DMB = α, α′- di(3-methylimidozole-1-yl)benzene dichloride}. Single-crystal X-ray diffraction analysis shows 1 and 3 are 1D supramolecules, whereas 2 is mononuclear. Electrostatic interactions between the organic counteranions and inorganic moieties are present and do the contribution to the crystal packing. These compounds have been further characterized by IR spectroscopy and thermostability properties.

Six cation-templated halometal complexes and C–H activation of alkylene-bridged azoles

Six dication-templated complexes were discovered in efforts to investigate the effect of linear imidazolium-based template, 1,ω-bis(3,3′-methylimidazolium)alkyl dibromide, on pure inorganic halometal clusters. Complexes {[C4(Mim)2](Pb2I6)}n (1) (ω = 4), {[C1(Mim)2] (Ag2I4)}n (2) (ω = 1), {[C3(Mim)2](Ag2I4)}n (3) (ω = 3), and {[C4(Mim)2](Ag2I4)}n (4) (ω = 4) possess 1-D chain architecture with different organic cations trapped in it. Compound {[C3′(Mim)2](CuBr3)} (5) (ω = 3) contains the mononuclear anion (CuBr3)2− and intra-molecular coupled organic cation with the formed seven-membered ring. {[C2(Mim)2S2]2(Cu2I2)}n (6) (ω = 2) presents an infinite 2-D coordination polymer as the first representative polyrotaxane example featuring the biimidazolium thiolate cation ligand. All compounds were further characterized with IR spectra and thermal analysis properties. Four bis(N-heterocyclic carbene) precursors together with the cyclization and thiolation products were utilized to construct six dication-templated metal halides from 0,1 to 2-D polypseudorotaxane.

The self-assembly reaction of metal halides with DDTD dication (DDTD = 5,8 -Diazoniadispiro[4.2.4.2] tetradecane) yielded three novel organic-inorganic hybrid mental halides (DDTD)[Zn(N3)3Cl] (1), (DDTD)[Hg2Br6] (2), and (DDTD)[Cd4(N3)6(Cl)8] (3), which are characterized by X-ray crystallography and IR spectroscopy. The crystal structures of 1–3 show that they all crystallize in monoclinic systems. Compound 1 is mononuclear complex, compound 2 is binuclear complex, and compound 3 is a tetranuclear polymer. These compounds contained a variety of inorganic frameworks, due to the different coordinated modes of metal centers with halogen, which accordingly led to the change of the C-H···Cl(Br) interactions in the complexes.
