The thermal DSC, TMA, DTG and DTA analyses indicate two solid-to-solid structural phase transitions (PTs). According to the X-ray diffraction experiments, the first PT at 220 K is isostructural, since it does not involve a change of the space group. This transition occurs between the states, where the (CH3)2NH2+ cations are orientationally disordered and ordered (frozen). The other reversible PT at 481 K leads to a melt-like phase similar to the one observed in plastic crystals or polar liquids. Dielectric spectroscopy has been used to characterise the switching properties of the dipole moments in the vicinity of the PTs. Continuous-wave electron paramagnetic resonance spectroscopy was employed to investigate the effect of ordering on the local environment of the Cr3+ ions. We have also applied the quasielastic neutron scattering (QENS) technique as well as 1H NMR spectroscopy to measure the dynamics of the (CH3)2NH2+ cations residing in the inorganic framework. 000863682 536__ $$0G:(DE-HGF)POF3-6G15$$a6G15 - FRM II / MLZ (POF3-6G15)$$cPOF3-6G15$$fPOF III$$x0 000863682 536__ $$0G:(DE-HGF)POF3-6G4$$a6G4 - Jülich Centre for Neutron Research (JCNS) (POF3-623)$$cPOF3-623$$fPOF III$$x1 000863682 588__ $$aDataset connected to CrossRef 000863682 65027 $$0V:(DE-MLZ)SciArea-120$$2V:(DE-HGF)$$aCondensed Matter Physics$$x0 000863682 65017 $$0V:(DE-MLZ)GC-2004-2016$$2V:(DE-HGF)$$aBasic research$$x0 000863682 693__ $$0EXP:(DE-MLZ)SPHERES-20140101$$1EXP:(DE-MLZ)FRMII-20140101$$5EXP:(DE-MLZ)SPHERES-20140101$$6EXP:(DE-MLZ)NL6S-20140101$$aForschungs-Neutronenquelle Heinz Maier-Leibnitz $$eSPHERES: Backscattering spectrometer$$fNL6S$$x0 000863682 7001_ $$00000-0002-0682-4575$$aBator, G.$$b1 000863682 7001_ $$0P:(DE-HGF)0$$aZarychta, B.$$b2 000863682 7001_ $$0P:(DE-HGF)0$$aDziuk, B.$$b3 000863682 7001_ $$0P:(DE-HGF)0$$aRepeć, J.$$b4 000863682 7001_ $$00000-0001-5494-5729$$aMedycki, W.$$b5 000863682 7001_ $$0P:(DE-Juel1)131056$$aZamponi, M.$$b6$$ufzj 000863682 7001_ $$00000-0002-7062-7277$$aUsevičius, G.$$b7 000863682 7001_ $$00000-0002-2733-2270$$aŠimėnas, M.$$b8 000863682 7001_ $$0P:(DE-HGF)0$$aBanys, J.$$b9 000863682 773__ $$0PERI:(DE-600)1472887-4$$a10.1039/C8DT05082A$$gVol. 48, no. 13, p. 4190 - 4202$$n13$$p4190 - 4202$$tDalton transactions$$v48$$x0300-9246$$y2019 000863682 8564_ $$uhttps://juser.fz-juelich.de/record/863682/files/c8dt05082a.pdf$$yRestricted 000863682 8564_ $$uhttps://juser.fz-juelich.de/record/863682/files/c8dt05082a.pdf?subformat=pdfa$$xpdfa$$yRestricted 000863682 909CO $$ooai:juser.fz-juelich.de:863682$$pVDB$$pVDB:MLZ 000863682 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)131056$$aForschungszentrum Jülich$$b6$$kFZJ 000863682 9131_ $$0G:(DE-HGF)POF3-6G15$$1G:(DE-HGF)POF3-6G0$$2G:(DE-HGF)POF3-600$$3G:(DE-HGF)POF3$$4G:(DE-HGF)POF$$9G:(DE-HGF)POF3-6G15$$aDE-HGF$$bForschungsbereich Materie$$lGroßgeräte: Materie$$vFRM II / MLZ$$x0 000863682 9131_ $$0G:(DE-HGF)POF3-623$$1G:(DE-HGF)POF3-620$$2G:(DE-HGF)POF3-600$$3G:(DE-HGF)POF3$$4G:(DE-HGF)POF$$9G:(DE-HGF)POF3-6G4$$aDE-HGF$$bForschungsbereich Materie$$lVon Materie zu Materialien und Leben$$vFacility topic: Neutrons for Research on Condensed Matter$$x1 000863682 9141_ $$y2019 000863682 915__ $$0StatID:(DE-HGF)0400$$2StatID$$aAllianz-Lizenz / DFG 000863682 915__ $$0StatID:(DE-HGF)0420$$2StatID$$aNationallizenz 000863682 915__ $$0StatID:(DE-HGF)0430$$2StatID$$aNational-Konsortium 000863682 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS 000863682 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bDALTON T : 2017 000863682 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline 000863682 915__ $$0StatID:(DE-HGF)0310$$2StatID$$aDBCoverage$$bNCBI Molecular Biology Database 000863682 915__ $$0StatID:(DE-HGF)0600$$2StatID$$aDBCoverage$$bEbsco Academic Search 000863682 915__ $$0StatID:(DE-HGF)0030$$2StatID$$aPeer Review$$bASC 000863682 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bClarivate Analytics Master Journal List 000863682 915__ $$0StatID:(DE-HGF)0110$$2StatID$$aWoS$$bScience Citation Index 000863682 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection 000863682 915__ $$0StatID:(DE-HGF)0111$$2StatID$$aWoS$$bScience Citation Index Expanded 000863682 915__ $$0StatID:(DE-HGF)1150$$2StatID$$aDBCoverage$$bCurrent Contents - Physical, Chemical and Earth Sciences 000863682 915__ $$0StatID:(DE-HGF)9900$$2StatID$$aIF < 5 000863682 9201_ $$0I:(DE-Juel1)JCNS-FRM-II-20110218$$kJCNS-FRM-II$$lJCNS-FRM-II$$x0 000863682 9201_ $$0I:(DE-Juel1)JCNS-1-20110106$$kNeutronenstreuung ; JCNS-1$$lNeutronenstreuung $$x1 000863682 980__ $$ajournal 000863682 980__ $$aVDB 000863682 980__ $$aI:(DE-Juel1)JCNS-FRM-II-20110218 000863682 980__ $$aI:(DE-Juel1)JCNS-1-20110106 000863682 980__ $$aUNRESTRICTED
