20.500.12556/RUL-125478 Koordinacija polietra s tremi O-donorskimi atomi na kovinske ione Coordination of polyether with three O-donor atoms to metal ions Diglyme oziroma di(2-metoksietil)eter je polieter z molekulsko formulo C6H14O3. V molekuli diglyme so trije O-donorski atomi, zato smo predvidevali, da se v večini koordinacijskih spojin veže trovezno kelatno. Našo predpostavko je potrdil pregled baze podatkov Cambridge Structural Database (CSD, verzija 5.41). Molekula diglyme je zaradi rotacije okoli enojnih vezi fleksibilna, zato lahko v oktaedričnih kompleksih nastajajo tako fac kot mer izomeri, kar dokazujejo tudi opisane strukture kompleksnih spojin. Strukture koordinacijskih spojin v CSD kažejo, da se diglyme lahko veže tudi na druge načine: enovezno, dvovezno kelatno in mostovno. Opisali smo sintezne pogoje, ki omogočajo različne načine koordinacije molekule diglyme v kompleksih prehodnih elementov in kovin. Diglyme or di(2-methoxyethyl) ether is a polyether with the molecular formula C6H14O3. Since diglyme contains three O-donor atoms, we assumed that the most common coordination is the tridentate chelate. After reviewing Cambridge Structural Database (CSD, version 5.41), we verified our assumption. The diglyme molecule is flexible due to the rotation of the single bonds. Therefore, fac and mer isomers form in octahedral complexes, which was demonstrated in the described complex compounds. The structures of the coordination compounds in CSD show that diglyme can coordinate as a tridentate chelating ligand, besides it can coordinate in other ways, as a monodentate, bidentate chelating ligand and as a bridging ligand. We have described the synthesis conditions that allow different coordination modes of the diglyme molecule to complex transition elements and metals. koordinacijska spojina diglyme fac-mer izomerija kelatna vezava mostovna vezava coordination compound diglyme fac-mer isomerism chelate coordination bridging coordination true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2021-03-18 11:10:00 2021-03-18 11:10:04 2022-09-05 03:50:55 0000-00-00 00:00:00 2021 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 13681 55935235 Kanalec_Eva_-_Koordinacija_polietra_s_tremi_O-donorskimi_atomi_na_kovinske_ione.pdf Kanalec_Eva_-_Koordinacija_polietra_s_tremi_O-donorskimi_atomi_na_kovinske_ione.pdf 1 4D9A688BBC75933CAAF27592992AFD9F 5b33e7e01b565953ef1d8f47dd403af3a52b0d90685b014180089cdd88a81dda b7a75d76-a1bb-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=141200 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
