Magnetic behavior of MnPS3 phases intercalated by [Zn2L]2+ (LH2: macrocyclic ligand obtained by condensation of 2-hydroxy-5-methyl-1,3-benzenedicarbaldehyde and 1,2-diaminobenzene)

MAGNETIC BEHAVIOR OF LAMELLAR MnPS3 AND CdPS3 COMPOSITES WITH A PARAMAGNETIC MANGANESE(III) MACROCYCLIC GUEST

“…When the magnetic behavior of (1) and (3) is compared with that of the composite obtained by microwave assisted intercalation, (5), it is possible to state that the spontaneous magnetization observed in the potassium precursor is still present in this latter composite as a remnant magnetization. A similar phenomenon was observed for Zn II /Mn II composites as reported previously 40 . Nevertheless, the observed spontaneous magnetization at low temperatures is field dependent, being suppressed at high field (Figure 5a).…”

Macrocyclic ZnII and CuII complexes as guests of the hybrid composites based on the layered MnPS3 phase. Comparison of spectroscopic properties

“…From an optical point of view the MnPS 3 phase is almost a non-absorbing material. Furthermore, the intercalated K 0.4 Mn 0.8 PS 3 phase is a useful precursor, due to the existence of weak host-guest interactions between the interlamellar hydrated potassium ions and the layers of MnPS 3 , which allow the exchange of these with bulky species, such as coordination compounds [22,23]. The synthesis and structural characterization of macrocyclic complexes started forty years ago, as reported by Zanello et al [24]; these complexes present different properties such as optical, magnetic, and antimicrobial activity that can modify the initial properties of MnPS 3 [25][26][27][28].…”

Effects of the intercalation time on the dielectric properties of Na2xMn1−xPS3

“…Among the lamellar hosts, the thiophosphate MnPS 3 is wellknown for its ability to form intercalation compounds, called also nanocomposites, with a large variety of atoms like alkali-metals, rare-earth, organic molecules or even cationic binuclear macrocyclic complexes [1][2][3]. This occurs by means of a unique non-redox reaction based on the cation exchange between host and guest: in particular a fraction of the Mn 2+ intralayer cations leaves their sites while the guest species enter the van der Waals gaps.…”

The soobtained compounds are labeled like A 2x Mn 1Àx PS 3 where A is the guest species cation or molecule which is inserted between the MnPS 3 basic sandwiches. These last ones, indicated like S[Mn 2/ Manganese thiophosphate powders have been intercalated with sodium ions at two different intercalation times (150 min and 180 min) in order to evaluate the influence of this parameter on the dielectric properties of the obtained compounds labeled like Na 2x Mn 1Àx PS 3 .…”

In particular, dielectric permittivity measures have been carried out as a function of temperature (80 K-350 K) and frequency (20 Hz to 1 MHz) and compared with each other and with those of the pure matrix and of the Na 2x Mn 1Àx PS 3 compound corresponding to a 120 min intercalation time.…”
