Abstract
U sklopu ovog diplomskog rada otopinskom sintezom su priređene četiri nove 3D metaloorganske mreže (MOF-ovi) cinka(II) s 4,4'-bipiridinom (bipy) i L-treoninom (HThr) ili L-serinom (HSer): {[Zn4(μ-Thr)4(H2O)(μ-bipy)4(DMF)](NO3)4∙(DMF/H2O)}n (1 i 2), {[Zn2(μThr)2(μ-bipy)3](NO3)2∙2bipy∙2H2O)}n (3) i {[Zn2(µ-Ser)2(µ-bipy)3](NO3)2(DMF/H2O)}n (4). Difrakcijom rendgenskog zračenja na jediničnom kristalu određene su molekulske i kristalne strukture MOF-ova 1 – 4 te je istražen način vezanja L-treonina, L-serina i 4,4'-bipiridina na cink. Aminokiseline se u MOF-ovima koordiniraju na cinkove atome na tri načina: monodentatno, didentatno (kelatno) te tridentatno. 4,4'-Bipiridin i aminokiseline se u svim MOF-ovima ponašaju kao premošćujući ligandi. U spojevima se nalaze beskonačni 2D kanali kristalizacijskih molekula otapala (voda ili DMF) i nekoordiniranih iona ili molekula (nitratnih iona i/ili 4,4’-bipiridina) s volumnim udjelima u jediničnoj ćeliji od 36,8 − 50,6 %. MOF 3 je dodatno okarakteriziran infracrvenom spektroskopijom te termogravimetrijskom analizom.
Abstract (english)
As a part of this diploma thesis, four new 3D metal-organic frameworks (MOFs) of zinc(II) with 4,4'-bipyridine (bipy) and L-threonine (HThr) or L-serine (HSer) were synthesized by solution method: {[Zn4(μ-Thr)4(H2O)(μ-bipy)4(DMF)](NO3)4∙(DMF/H2O)}n (1 i 2), {[Zn2(μThr)2(μ-bipy)3](NO3)2∙2bipy∙2H2O)}n (3) and {[Zn2(µ-Ser)2(µ-bipy)3](NO3)2·(DMF/H2O)}n (4). The molecular and crystal structures of MOFs 1 − 4 were solved by the single-crystal Xray diffraction method and the mode of binding of L-threonine, L-serine, and the 4,4’-bipyridine on the zinc atoms has been explored. Amino acids are coordinated to the zinc atoms as monodentate, bidentate (chelating) or tridentate ligands. In all MOF-s, the 4,4’-bipyridine and amino acids are bridging ligands. Water or DMF solvent molecules and uncoordinated ions or molecules (nitrate ions and/or 4,4’-bipyridine) were captured in 2D channels of all four MOFs with a volume fraction of 36.8 − 50.6%. The MOF 3 is additionally characterized by infrared spectroscopy and thermogravimetric analysis.
