摘要: The novel coordination polymer [Co4(2,2′-bipy)4(H2O)2(btec)2]n (btec = 1,2,4,5-benzenetetracarboxylate), 1, has been hydrothermally synthesized. X-Ray diffraction experiments reveal that 1 exhibits an interesting two-dimensional (2D) chiral undulated (6,4)-network, which represents the first example of a 2D containing two kinds organic ligands. value Flack parameter, x = 0.52(2), shows crystal is inversion twin approximately 50% right-handed and left-handed structure whole compound racemate. Variable temperature magnetic susceptibility indicates antiferromagnetic interactions exist between metallic Co(II) centers in 1.
