“…The development of laboratory instrumentation and software tools has made high-quality solid-state instrumental analysis techniques, such as powder X-ray diffraction (PXRD), 39 solid-state NMR (SSNMR) 40 and solid-state infrared attenuated total reflection spectroscopies (FTIR-ATR) commonplace in many chemistry departments and laboratories. Particularly impressive developments have been made in algorithms and software for structure determination from PXRD data.…”

Abstract. This review briefly discusses recent advances and future prospects in the mechanochemical synthesis of coordination compounds by ball milling and grinding, and highlights our contributions to the mechanosynthesis of porous metal-organic frameworks (MOFs) and zeolitic imidazolate frameworks (ZIFs), metal-organic pharmaceutical derivatives and metallodrugs using the recently developed mechanochemical methods of liquid-assisted grinding (LAG) and ion-and liquid-assisted grinding (ILAG). The role of mechanochemistry in the development of a solvent-free laboratory, cocrystal synthesis and new materials for luminescence and gas absorption is also highlighted. (doi: 10.5562/cca2014)

“…They also provide the possibility to study a comprehensive set of materials including diamagnetic (NMR), magnetically diluted (EPR) and magnetic samples (Raman) [38][39][40]. This study re-examines data from BaZnF 4 (NMR and Raman) and extends the study to BaZn This paper reports experimental data that favours a discontinuous change in structural distortion of fluoride octahedra based on observed temperature changes in the Zero Field Splitting parameters |D| and |E| extracted from EPR spectra.…”

The local nuclear and electronic structures and molecular dynamics of the ferroelectric lattice in selected geometric fluorides (BaMgF 4 , BaZnF 4 , BaMg 1−x Mn x F 4 and BaMg 1−x Ni x F 4 ; x = 0.001 and 0.005) have been investigated. The 19 F and 25 Mg isotropic chemical shift δ iso , 25 Mg quadrupolar coupling constants (C q ) and asymmetry parameters (η) reflect the geometry of the coordination spheres. The zero-field splitting parameters |D| and |E| are consistent with distorted axial symmetry (low temperatures) and nearly rhombic symmetry (high temperatures) of octahedral Mn 2+ coordination. The high resolution of the nuclear magnetic resonance, electron paramagnetic resonance and phonon spectra are consistent with the highly ordered crystallographic structure. Combined multi-technique data evidence the subtle discontinuous changes in the temperature dependences of |D| and |E|, isotropic chemical shifts δ iso and signature parameters of Raman bands and suggest a discontinuous structural distortion of the fluoride octahedra. The temperature at which this change occurs depends on the ionic radius of the central ion of the octahedral site and is estimated to be ∼300 K for Zn 2+ fluorides and ∼240 K for Mg 2+ fluorides. This geometrical distortion modifies the lattice dynamics and originates from the rotation of the fluoride octahedra around a new direction approximately perpendicular to that related to the paraelectric-ferroelectric phase transition.
