Abstract

Hibridni organsko-anorganski halogenometalati (HOAH) privlače pažnju šire znanstvene zajednice s obzirom na izuzetna svojstva koje ti materijali potencijalno mogu imati, poput fotonaponskih, optičkih, električnih i magnetskih. U okviru ovog diplomskog rada ispitana je sinteza HOAH spojeva s manganom(II) kao metalnim centrom, kloridnim i bromidnim anionima kao ligandima te organskim kationima izvedenima iz odabranih triamina i tetraamina (dietilentriamin, DETA; N-(2-aminoetil)propan-1,3-diamin, N-P-1,3-DA i trietilentetraamin, TETA). Klasičnom otopinskom sintezom priređeni su hibridni organsko-anorganski halogenomanganati(II): (H3DETA)[MnCl5], (H3[N- P-1,3-DA])[MnCl5] i (H4TETA)[MnCl6]. Uz to, provedena je i sinteza halogenidnih soli (klorida i bromida) istih triamina i tetraamina: (H3DETA)Cl3, (H3[N-P-1,3-DA])Cl3, (H3[N-P-1,3-DA])Br3, (H4TETA)Cl4, (H4TETA)Br4 te (H4TETA)Br4·H2O. Priređeni spojevi okarakterizirani su FT-IR spektroskopijom, metodama termičke analize te difrakcijom rendgenskog zračenja na polikristalu i monokristalu. Pripravljeni kloromanganati(II) pripadaju skupini slojevitih 2D HOAH, gdje se između anorganskih slojeva kloromanganatnih(II) jedinki ugrađuju organski kationi.

Abstract (english)

Hybrid organic-inorganic halometalates (HOIHs) are currently in the spotlight of the wider scientific community due to the exceptional photovoltaic, optical, electrical and magnetic properties that these materials might display. Within the framework of this diploma thesis, synthesis of HOIH compounds with manganese(II) metal center, chloride and bromide anions as ligands and organic cations derived from triamines and tetraamines (diethylenetriamine, DETA; N-(2-aminoethyl)propane-1,3-diamine, N-P-1,3-DA and triethylenetetramine, TETA) was examined. By solution synthesis hybrid organic- inorganic halomanganates(II): (H3DETA)[MnCl5], (H3[N-P-1,3-DA])[MnCl5] and (H4TETA)[MnCl6] were prepared. In addition, the halide salts (chlorides and bromides) of the same triamines and tetraamines: (H3DETA)Cl3, (H3[N-P-1,3-DA])Cl3, (H3[N-P-1,3-DA])Br3, (H4TETA)Cl4, (H4TETA)Br4 and (H4TETA)Br4·H2O were synthesized. Compounds were characterized by FT-IR spectroscopy, thermal analysis and X-ray diffraction. Prepared hybrid chloromanganates(II) belong to the class of layered HOIHs.
