| 英文摘要 | Four zn, cd and mn based 1,10-phenanthroline and halogenated benzoic acid coordination compounds, formulated as zn2(ii)(h2o)(3)(phen)(so4)center dot h2o (1, phen = 1,10-phenanthroline), zn-ii(phen)(l-2)(2)(h2o) (2, l-2 = 2-chloro-4-fluorobenzoic acid), mn-iv(phen)(l-1)(4) (3, l-1 = 2-chloro-4,5-difluorobenzoic acid) and cd-ii(phen)(2)(no3)(2) (4), were successfully synthesized and structurally characterized. the low temperature heat capacities of these four compounds were further investigated using a physical property measurement system calorimetric method. the experimental heat capacities were fitted to a series of theoretical and empirical heat capacity models, and the corresponding thermodynamic functions were calculated in the temperature range from (0 to 300) k based on these models and fitting parameters. the low temperature fits indicated that compound 1 can be modeled using only lattice heat capacity contribution, compound 3 modeled using lattice and a(.2) term or schottky heat capacity contributions, and compound 2 and 4 modeled using contributions from lattice, vacancies and one-dimensional phonons with a finite energy onset or gap. |
