Dielectric Anisotropy of a Homochiral Trinuclear Nickel(II) Complex

Tetrakis(4-chloroanilinium) hexachloridostannate(IV) dichloride

“…The study of ferroelectric materials has received much attention; some of them have predominantly dielectricferroelectric performance (Ye et al, 2006;Fu et al, 2007;Zhao et al 2008;Zhang et al, 2008;Ye et al, 2009). As a part of our work to obtain potential ferroelectric phase-transition material, we report herein on the crystal structure of title compound.…”

“…For general background to ferroelectric metal-organic frameworks, see: Ye et al (2009) ;Fu et al (2007). For phase transitions in ferroelectric materials, see : Zhang et al (2008); Zhao et al (2008); Ye et al (2006).…”

Noncentrosymmetric Inorganic Oxide Materials: Synthetic Strategies and Characterisation Techniques

“…[145] It is important to know that the claim of ferroelectricity has been made for a number of materials based on the observation of a closed hysteresis loop. [146][147][148][149][150] An excellent article by Scott has recently appeared that describes this 'false ferroelectricity'. [151] In this paper, he describes how some reported ferroelectric loops are simply from lossy dielectrics and have nothing to do with polarisation reversal.…”

Two d10 coordination polymers based on 4,4′-(hexafluoroisopropylidene)diphthalic acid: Syntheses, structures and physical properties

“…80-150 lm indicate that 2 is SHG active with a value approximately 15 times larger than that of KH 2 PO 4 (KDP). [39] The space group Fdd2 is associated with the point group C 2v , one of the 10 polar point groups (C 1 , C s , C 2 , C 2v , C 3 , C 3v , C 4 , C 4v , C 6 , C 6v ) required for ferroelectric behavior [40]. Experimental results indicate that 2 does indeed display ferroelectric behavior.…”
