Dimension-Dependent Phase Transitions, Ferroelasticity, and Photoluminescence in Hybrid Organic-Inorganic Materials.

[(CH)P(CH)OH]Cd(SCN) () and [(CH)P(CH)OH]Cd(SCN) () were obtained with completely different structures and properties under the same synthesis conditions. Compound , showing green fluorescence, has a rare three-dimensional 4,6-connected fsh topology having (4.6)(4.6.8) Schläfli notation, while compound with blue-violet phosphorescence displays a one-dimensional perovskite structure with an infinite {[Cd(SCN)]} chain and exhibits both ferroelastic and dielectric switching characteristics.
