摘要：
Infrared and Raman vibrational spectroscopies were employed to explore the lattice dynamics of [Ru-2(O2CMe)(4)](3)[Cr(CN)(6)] through the field- and temperature-driven magnetic transitions. The high field work reveals systematic changes in the C equivalent to N stretching mode and Cr-containing phonons as the system is driven away from the antiferromagnetic state. The magnetic intersublattice coalescence transition at B-c similar or equal to 0.08 T, on the contrary, is purely magnetic and takes place with no lattice involvement. The variable temperature spectroscopy affirms overall [Cr(CN)(6)](3-) flexibility along with stronger intermolecular interactions at low temperature. Based on a displacement pattern analysis, we discuss the local lattice distortions in terms of an adaptable chromium environment. These findings provide deeper understanding of spin-lattice coupling in [Ru-2(O2CMe)(4)](3)[Cr(CN)(6)] and may be useful in the development of technologically important molecule-based magnets.
