Abstract

U okviru ovog diplomskog rada su pripravljene kloridne i bromidne soli alifatskih diamina 1,3-
diaminopropan-2-ola (H2(DPOH)Cl2 i H2(DPOH)Br2), propan-1,2-diamina (H2(1,2-DAP)Cl2 i H2(1,2-
DAP)Br2) i propan-1,3-diamina (H2(1,3-DAP)Cl2 i H2(1,3-DAP)Br2). Reakcijom pripravljenih soli
diamina te bakrovog(II) klorida ili bakrovog(II) bromida priređena je serija slojevitih hibridnih organskoanorganskih
halokuprata(II), H2(DPOH)[CuCl4], H2(DPOH)[CuBr4], H2(1,3-DAP)[CuCl4], H2(1,3-
DAP)[CuBr4] te... More H2(1,2-DAP)[CuCl4]). Svi priređeni hibridni halometalati imaju slojevitu strukturu u
kojoj dolazi do interkaliranja organskih kationa (kationa alifatskih diamina) između anorganskih
slojeva. Anorganski sloj je građen od jedinki oktaedarske građe kod kojih je Cu(II) kation okružen sa
šest kloridnih ili bromidnih iona. Sve strukture pripadaju Dion-Jacobson (DJ) fazi u kojima se organski
kationi nalaze u monosloju, a povezani su vodikovim vezama s anorganskim slojevima. Zbog vodikovih
veza, dolazi do efekta „boranja“ anorganskih slojeva. Spojevi su identificirani i okarakterizirani na
temelju podataka infracrvene spektroskopije, difrakcije rendgenskog zračenja na polikristalnom uzorku,
metodama termičke analize te u slučajevima kada je to bilo moguće difrakcijom rendgenskog zračenja
na jediničnom kristalu. Metode termičke analize ne ukazuju na postojanje faznog prijelaza prve vrste,
ali nelinearna promjena geometrijskih parametara sugerira kako dolazi do faznih prijelaza druge vrste. Less

Abstract (english)

Within this diploma work, chloride and bromide salts of aliphatic diamines 1,3-diaminopropan-2-ol
(H2(DPOH)Cl2 and H2(DPOH)Br2), propane-1,2-diamine (H2(1,2-DAP)Cl2 and H2(1,2-DAP)Br2) and
propane-1,3-diamine (H2(1,3-DAP)Cl2 and H2(1,3-DAP)Br2) were prepared. A series of layered hybrid
organic-inorganic halocuprates(II), H2(DPOH)[CuCl4], H2(DPOH)[CuBr4], H2(1,3-DAP)[CuCl4],
H2(1,3-DAP)[CuBr4] and H2(1,2-DAP)[CuCl4] was prepared by the reaction of prepared diamine salts
and copper(II)... More chloride or copper(II) bromide. All prepared hybrid halometalates have a layered structure
in which there is intercalation of organic cations (cations of aliphatic diamines) between inorganic
layers. The inorganic layer is composed of units of octahedral structure in which the Cu(II) cation is
surrounded by six chloride or bromide ions. All structures belong to the Dion-Jacobson (DJ) phase in
which organic cations are found in a monolayer and are linked by hydrogen bonds to inorganic layers.
Due to hydrogen bonds, there is an effect of "wrinkling" of inorganic layers. Compounds were identified
and characterized by means of infrared spectroscopy, X-ray powder diffraction, thermal analysis and
when it was possible via single-crystal X-ray diffraction. Thermal analysis methods do not indicate the
existence of a phase transition of the first type, but a nonlinear change in the geometric parameters
suggests that phase transitions of the second type occur. Less
