Abstract

U okviru ovog diplomskog rada pripravljene su halogenidne soli alifatskih triamina dietilentriamina ((H3DETA)Cl3), N-(2-aminoetil)-1,3-propandiamina ((H3N-1,3-PDA)Cl3 i (H3N-1,3-PDA)Br3) kao i kloridna sol trietilentetraaamina ((H4TETA)Cl4). Klasičnom otopinskom sintezom pripravljena je serija hibridno organsko-anorganskih halogenokuprata(II): (H3DETA)[CuCl5], (H3DETA)[CuBr5], (H3N-1,3-PDA)[CuCl5], (H3N1,3-PDA)[CuBr5], (H4TETA)[CuCl6] i (H4PEEA)[CuBr6]·H2O. Anorganske građevne jedinke kod svih priređenih halogenometalata su stehiometrije CuX4, te se većinom udružuju u slojevite okosnice. Kod hibridnih halogenometalata sa slojevitom strukturom dolazi do ugrađivanja organskih kationa između anorganskih slojeva. Organski kationi povezuju se putem protoniranih terminalnih amino skupina za halogenokupratne(II) jedinke, a međusobno se udružuju putem N‒H···X···H‒N vodikovih veza. Pripravljenim hibridnim halogenometalatima određene su kristalne strukture pomoću difrakcije rendgenskog zračenja na jediničnom kristalu, a spojevi su dodatno okarakterizirani pomoću infracrvene spektroskopije, difrakcije rendgenskog zračenja na polikristalnom uzorku te metodama termičke analize.

Abstract (english)

In this work, halide salts of aliphatic triamines diethylenetriamine, ((H3DETA)Cl3), N-(2- aminoethyl)-1,3-propanediamine, (H3N-1,3-PDA)Cl3 and (H3N-1,3 -PDA)Br3, and the chloride salt of triethylenetetraamine, (H4TETA)Cl4, were prepared. A series of hybrid organic-inorganic halocuprates(II) were prepared by solution crystallization:
(H3DETA)[CuCl5], (H3DETA)[CuBr5], (H3N-1,3-PDA)[CuCl5], (H3N-1,3-PDA)[CuBr5],
(H4TETA)[CuCl6] and (H4PEEA)[CuBr6]·H2O. The inorganic building blocks of all prepared halogenometalates have stoichiometry CuX4, and they are mostly combined into layered frameworks. In the case of hybrid halometallates with a layered structure, organic cations are incorporated between the inorganic layers. Organic cations are connected via protonated terminal amino groups to halocuprate(II) units, and interlinked to each other via N‒ H···X···H‒N hydrogen bonds. The crystal structures of the prepared hybrid halogenometalates were determined using single-crystal X-ray diffraction, and the compounds were additionally characterized using infrared spectroscopy, powder X-ray diffraction and thermal analyses.
