New polymorphs β and γ of bis-3-nitrophenyl disulphide, crystallized above 0.3 GPa, are less dense than the ambient-pressure polymorph α. This counterintuitive density relation results from the high-entropy nucleation and subsequent kinetic crystallization. The work performed by pressure compensates the high entropy and temperature product, substantiated in varied conformers and increased chemical potential. Pressure-increased viscosity promotes the kinetic polymorphs, in accordance with empirical Ostwald's rule of stages. It contrasts to mechanochemical techniques, favouring high-density polymorphs. 相似文献

We report on reactions of heteroleptic metallasilylenes L1(Cl)MSiL2 (M=Al 1 , Ga 2 , L1=HC[C(Me)NDipp]2, Dipp=2,6-iPr2C6H3; L2=PhC(NtBu)2) with CO2, N2O, and Me3SiN3, yielding the corresponding carbonate complexes L1(Cl)MOSi(CO3-κ2O,O−)L2 (M=Al 3 , Ga 4 ), silanoic esters L1(Cl)MOSi(O)L2 (M=Al 5 , Ga 6 ), and silaimine L1(Cl)GaSi(NSiMe3)L2 ( 8 ), whereas {L2Si[N(SiMe3)Al(Cl)C(Me)NDipp][CHC(Me)N(Dipp)]} 7 was formed by C−C bond cleavage of the L1 ligand. Compounds 3 – 8 were characterized by NMR (1H, 13C) and IR spectroscopy, elemental analysis and single crystal X-ray diffraction. 相似文献
