Two unprecedented 1D coordination polymer chains based on tetranuclear copper(II) building blocks
چکیده انگلیسی

The reaction of copper(II) sulfate with pyridine in DMF or methanol yield two unprecedented Cu(II) coordination polymers {[Cu4(μ4–O)(py)4(SO4)4][μ–Cu(py)(DMF)2]}n(1) and {[Cu4(μ4–O)(py)4(SO4)4][μ-Cu(py)4]}n(2), respectively. Single-crystal X-ray diffraction indicated that compound 1 crystallizes in the monoclinic system, space group p2(1)/n, a=14.542(5) Å, b=16.359(5) Å, c=18.951(5) Å, β=92.047(5)°, V=4505(2) Å3, Z=4 while 2 is monoclinic C2/c, a=23.078(5) Å, b=10.214(5) Å, c=23.142(5) Å, β=115.471(5)°, V=4925(3) Å3, Z=4. Both of the two compounds consist of tetrahedral tetranuclear [Cu4(μ4–O)(py)4(SO4)4] clusters that are bridged by pentacoordinated Cu atom for 1 or hexacoordinated Cu atoms for 2 through the sulfate oxygen to form the infinite one-dimensional polymer chains.

Two unprecedented Cu(II) coordination polymers have been prepared by using solvothermal method; they consist of tetrahedral tetranuclear clusters that are bridged by unique Cu(II) atom through the sulfate oxygen to form the infinite one-dimensional polymer chains (a) for complex 1 and (b) for complex 2.Figure optionsDownload as PowerPoint slide
