Nickel（II） complexes Ni（L1）2 （1） and Ni（L2）2·CH3CN·H2O （2） （L1Cl = 2-（3-benzyl- 2,3-dihydroimidazlo-1-yl）-N-（pyridin-2-yl）acetamide, chloride salt, L2Cl = 2-（3-naphthalene-2- ylmethyl）-2,3-d...Nickel（II） complexes Ni（L1）2 （1） and Ni（L2）2·CH3CN·H2O （2） （L1Cl = 2-（3-benzyl- 2,3-dihydroimidazlo-1-yl）-N-（pyridin-2-yl）acetamide, chloride salt, L2Cl = 2-（3-naphthalene-2- ylmethyl）-2,3-dihydro-imidazlo-1-yl）-N-phenylacetamide, chloride salt） with amide-functionalized imidazolium NHC ligand were synthesized and determined by single-crystal X-ray diffraction. Complex 1 crystallizes in the monoclinic system, space group P21/cwith a = 9.2561（19）, b = 15.138（3）, c = 20.750（4） A, β = 90.216（3）°, V = 2907.3（10） A^3 and Z = 4. Complex 2 crystallizes in the orthorhombic system, space group Pbca with a = 15.5469（16）, b = 15.3521（15）, c = 31.177（3） A, V = 7441.2（13） ？3 and Z = 8. They are stable in the air and formed via intermolecular weak interactions, including C-H···π contacts and C–H···O hydrogen bonds. Complex 1 was applied in Suzuki coupling reaction through the investigation of reaction conditions under the optimal choice conditions： 80 ℃, K3PO4, 3% mol catalysts, 6% mol PPh3 and toluene as solvent system could afford 96% yield in 5 h.展开更多
In this study, two new co-crystals based on rigid imidazolium ligand （2,2＇-（（1,1’- biphenyl）-4,4＇-diyl）bis（2H-imidazo[1,5-a]pyridine-4-ium） hexafluorophosphate （L）） and 4,4＇- bipyridine （Bpy） and benze...In this study, two new co-crystals based on rigid imidazolium ligand （2,2＇-（（1,1’- biphenyl）-4,4＇-diyl）bis（2H-imidazo[1,5-a]pyridine-4-ium） hexafluorophosphate （L）） and 4,4＇- bipyridine （Bpy） and benzene （Ben）, formulated as L（Bpy）0.5 （co-crystal 1） and L（Ben） （co-crystal 2）, were obtained. Crystal data for 1： Pī space group with α = 10.921（4）, b = 16.998（6）, c = 17.666（6） A, α = 95.720（7）, β = 104.272（7）, γ = 93.340（6）°, V = 3150.5（19） A^3 and Z = 2; and crystal data for 2： monoclinic C2/m space group with α = 25.90（2）, b = 9.631（9）, c = 6.371（6） A, β = 95.26（2）°, V = 1583（2） A3 and Z = 2. Co-crystal 1 was dependent on hydrogen bonds and π···π stacking, while only hydrogen bonds are present in 2. Two new co-crystals were characterized by IR, NMR spectra, thermogravimetric and ultraviolet absorption analyses.展开更多
