Copper(II) and cobalt(II) dicarboxylate-based layered magnets: influence of π electron ligands on the long range magnetic ordering

A Novel Three-Fold Interpenetrating Three-Dimensional Co(II) Coordination Polymer Based on Flexible Bistriazole Ligand: Synthesis, Structure and Magnetic Properties

“…This is due to the significant orbital contribution of the octahedral Co(II) ions. As the temperature decreases, χMT value gradually decreases and reaches a minimum of 2.05 cm To investigate the magnetic properties, the simple phenomenological equation and the fitting method therein can be used for roughly estimating the spin-orbit coupling and the magnetic exchange of complex 1 in the lower temperature range [23][24][25]. The magnetic data were roughly fitted with the simple phenomenological equation: (Fig.…”

Lead(II) Hybrid Materials from 3‐ or 4‐Phosphonobenzoic Acid

“…Hybrid organic-inorganic materials have been widely studied in the recent past for their promising applications in different fields including catalysis, [1] magnetism, [2] gas storage, [3] optic [4] and luminescence. [5] It is now established that the optimization of the properties of such materials is intimately connected to a better understanding of their architecture.…”

“…The current way used for hybrid construction consists of synthesizing organic precursors possessing the required shape, flexibility, number and type of reactive functional groups (e.g., carboxylate, [6] phosphonic acids [7] , ...) and to select the metallic centre for its coordination number, geometry and its intrinsic properties (e.g., magnetism and luminescence). As an example, the reaction of phenyl phosphonate [C 6 H 5 PO(OH) 2 ] with magnetic divalent salts provides access to a series of layered magnetic phosphonates M 2+ (RPO 3 )·H 2 O (R = phenyl and M 2+ = Mn, Fe, Co, and Ni) which exhibit a 2D antiferomagnetism behaviour at low 4870 duced materials have been solved by means of single-crystal X-ray diffraction data. It was observed that the use of the 4-phosphonobenzoic acid produces the hybrids 2, 3, or 4 that possess a layered structure.…”

“…The exploration and the knowledge of the structure of such frameworks are of great interest to a better understanding of the physico-chemical properties of lead materials (e.g. luminescent properties [25] 2 (m-PO 3 C 6 H 4 CO 2 ) 2 ] (1) which has been obtained by using 3-phosphonobenzoic acid as organic precursor and for which the X-ray structure has been very recently reported by Fang et al [22] Finally the ATG and Scanning Electron Microscopy of all these materials are reported and discussed.…”

Quantitative Analyses of Shape-Selective Intercalation of Isomeric Mixtures of Muconates into [LiAl2(OH)6]Cl·yH2O Layered Double Hydroxide

“…Muconates, 2,4-hexadienedioates which can be one of the guest anions, exist as three geometric isomers: (Z ,Z ), (E,Z ), and (E,E) forms. However, hybrid organic-inorganic layered materials containing muconates are scare (33)(34)(35). These muconate anions can be used as a bridge species of hybrid organic-inorganic multilayer materials because of their conjugated π system which may play an important role in controlling the long-range physical interaction by electronic communication between adjacent inorganic layers.…”
