Assembly reactions of orotic acid (H{sub 3}dtpc ) and CdCl{sub 2}.2.5H{sub 2}O or CdSO{sub 4}.8H{sub 2}O yielded four new cadmium compounds {l_brace}[Cd(H{sub 2}dtpc)(phen)(H{sub 2}O){sub 2}].(H{sub 2}dtpc).4H{sub 2}O{r_brace}{sub 2} (1: solution reaction, pH=4-5, in addition of phen), [Cd{sub 3}(dtpc){sub 2}(phen){sub 5}].13H{sub 2}O (2: hydrothermal reaction, initial pH=14, final pH=7.5), [Cd(Hdtpc)(H{sub 2}O){sub 3}]{sub 4} (3: solution reaction, initial pH=6.5, final pH=6.0), {l_brace}[Cd(Hdtpc)(phen)(H{sub 2}O)].H{sub 2}O{r_brace}{sub n} (4: hydrothermal reaction, initial pH=8; final pH=6.5), respectively. Compounds 1-4 have been characterized by IR, thermogravimetric analyses (TGA), photoluminescence analyses, single-crystal and powder X-ray diffraction (PXRD). Compound 1 is a binuclear, 2 is a trinuclear, 3 is a tetranuclear structure, and 4 possesses one-dimensional chain framework, respectively, in which the orotate ligands show seven different linking fashions in 1-4. The orotate ligands as trivalence anions are observed in the formation of orotate-compounds, in which the orotates show high stability under the extreme condition of strong basic solution, high temperature and pressure. - Graphical abstract: Assembly of orotic acid and Cd(II) salts result in four new compounds under different reaction conditions, the compounds possess strong photoluminescence emissions and high thermal stability. Highlights: > Four Cd-compounds were prepared from orotic acid under different crystallization systems. > The orotates as trivalence anions displayed high stability under extremely conditions. > The orotates displayed various connection modes in the compounds. > The strong photoluminescence emissions have been observed in the compounds.
