X-Ray Crystal Structure of a Novel 2D Mn(II) Coordination Polymer with 4,4′-trimethylenedipyridine and 3-nitrophthalate as Ligands

Oxidation-induced phase transformations of hybrid tin bromide single crystals enable the occurrence of second-harmonic generation

“…Similarly, inorganic components in TMDPSnBr 6 single crystals are changed after phase transformations, and the coordination number of tin atoms is from 3 to 6, and the order arrangements of TMDP 2+ were also broken. TMDP 2+ cations in TMDPSn 2 Br 6 were originally in the TT conformation, 32 and changed into the GG′ conformation in TMDPSnBr 6 , as shown in Fig. S2b †.…”

“…S12 and S13, † there are five different types of NMR-active carbon nuclei, and there are two aliphatic carbon peaks between 20 and 40 ppm of the chemical shift (d) and three aromatic carbon peaks from 120 to 170 ppm, which is generally similar to the previous report. 31 The chemical shift changes in 13 C-NMR and 1 H-NMR spectra of TMDPSnBr 6 are attributed to the conformational change of the TMDP molecule (TT conformation → GG′ conformation) caused by the phase transformations, 32 as shown in Fig. S14 and S15.…”
