Variable-temperature solid-state 2H NMR spectra have been recorded on microcrystalline samples of [Mo(η-C6D6)2], [Mo{η-C6D3(CD3)3-1,3,5} 2] and [ZrS2{Mo[η-C6D3(CD3) 3-1,3,5]2}0.15]. In the case of [Mo(η-C6D6)2] the spectra are invariant in the ra

Solid state 2H NMR spectra of single crystal samples of CdPS3{Co(η-C5D5)2}0.4 indicate the co-existence of both Co(η-C5D5)2 and [Co(η-C5D5)2]+between the CdPS3layers; all the metallocene guest molecules reside in ordered domains within the ab-plan

The orientations of [Co(C5D5)2] + ions intercalated in the xerogel V2O5· 1.6H2O have been studied using solid-state 2H NMR spectroscopy. The cobaltocenium ions in microcrystalline samples of V 2O5{Co(C5D5)2} 0.2(H2O)0.5 are observed to be held rigid

Variable-temperature 13C CPMAS NMR spectra of the metal–carbonyl complexes FeCp(CO)2X (where X = I, CH3) and Mo2Cp2(CO)6 included in β- or γ-cyclodextrin (CD) cavities were investigated in the temperature range 133 to 293 K. The motion of the gue

207Pb NMR spectroscopy was used to investigate 20 lead(IV) tetracarboxylates both in solution and in the solid state by cross-polarization magic angle spinning (CP/MAS) NMR. There is generally good correlation between isotropic chemical shifts in the

The deoxycholic acid inclusion complex (DCA) 2 :ferrocene (1) undergoes a gradual phase transition above ambient temperature, completed by ∼360 K. The phase transition is characterized by using single-crystal X-ray diffraction and 13 C CP/MAS NMR s
