Magnetic properties of the Haldane-gap material [Ni(C₂H₈N₂)₂NO₂](BF₄)

Results of magnetization and high-field electron spin resonance (ESR) studies of the new spin-1 Haldane-chain material [Ni(C2H8N2)2NO2] (BF4) (NENB) are reported. A definite signature of the Haldane state in NENB was obtained. From the analysis of the frequency–field dependence of magnetic excitations in NENB, the spin-Hamiltonian parameters were calculated, yielding 1/kB = 17.4 K, g‖ = 2.14, D...

Anion-Induced Self-Assembly of Luminescent and Magnetic Homoleptic Cyclic Tetranuclear Ln₄(Salen)₄ and Ln₄(Salen)₂ Complexes (Ln = Nd, Yb, Er, or Gd)

Unique homoleptic cyclic tetranuclear Ln4(Salen)4 complexes [Ln4(L)2(HL)2(μ3-OH)2Cl2]·2Cl (Ln = Nd, 1; Ln = Yb, 2; Ln = Er, 3; Ln = Gd, 4) or Ln4(Salen)2 complexes [Ln4(L)2(μ3-OH)2(OAc)6] (Ln = Nd, 5; Ln = Yb, 6; Ln = Er, 7; Ln = Gd, 8) have been self-assembled from the reaction of the hexadentate Salen-type Schiff-base ligand H2L with LnCl3·6H2O or Ln(OAc)6·6H2O (Ln = Nd, Yb, Er, or Gd), respe...

IR Spectroscopic Study of M ( Benzoic Acid ) 2 Ni ( CN ) 4 · ( 1 , 4 - Dioxane ) Clathrate ( M = Ni , Cd and Co )

In various studies, Hofmann-type clathrates, given by the general formula ML2Ni(CN)4·G, were produced. Here M is a transition metal atom, L a ligand molecule or half of a bidentate ligand molecule, and G a guest molecule [1]. The clathrates are of interest because of their inclusion behavior and use as catalysts, anti-oxidants and stabilizing agents [2]. Infrared spectroscopy is one of the best...
