trinuclear pivalates Fe 2 MO(Piv) 6 (Hpiv) 3 (M = Ni II or Co II , Piv = (CH 3 ) 3 CCO 2 − ) with pyridine-containing ligands – trans -bis-1,2-(4-pyridyl)ethylene ( trans -dpe), bis-1,3-(4-pyridyl)propane (py 2 Pn) resulted in formation of 2D porous coordination polymers [Fe 2 NiO(Piv) 6 ( trans -dpe) 1.5 ] n ( 1 ), [Fe 2 CoO(Piv) 6 ( trans -dpe) 1.5 ] n ( 2 ) and 1D polymers [Fe 2 CoO(Piv) 6 ( cis
摘要研究表明,三核新戊酸酯Fe 2 MO(Piv)6(Hpiv)3(M = Ni II或Co II,Piv =(CH 3)3 CCO 2-)与含吡啶的配体–反-双- 1,2-(4-吡啶基)乙烯(反式-dpe),双-1,3-(4-吡啶基)丙烷(py 2 Pn)导致形成2D多孔配位聚合物[Fe 2 NiO(Piv)6(反式-dpe)1.5] n(1),[Fe 2 CoO(Piv)6(反式-dpe)1.5] n(2)和1D聚合物[Fe 2 CoO(Piv)6(顺式-dpe)} 2(反式-dpe)] n(3),[Fe 2 NiO(Piv)6(py 2 Pn)(DMF)] n(4),其中顺式-dpe为顺式-双-1,2-(4-吡啶基)乙烯,是由于反式-dpe的原位异构化而形成的。Fe 2 NiO(Piv)6(Hpiv)3与双2,3-(4-吡啶基)-2,3-二羟基丁烷的相互作用导致该配体的原位破坏和三核复合物Fe
