Singlecrystal ac susceptibility measurements on [Co(NH3)6][CuCl5], a 3D, S=1/2 Heisenberg antiferromagnet

Crystal Structure and Magnetic Properties of Bis(N,N-dimethyl-2-thiophenemethylammonium) Tetrabromocobaltate(II)

“…3,12,18,28 The strength of these interaction, which are invariable antiferromagnetic, decreases rapidly with the BrBr distance. 14 The room temperature magnetic moment of the (dmamtH) 2 -CoBr 4 complex is 4.69 BM and is typical for noninteracting or weak interacting high spin d 7 cobalt ions. The effective magnetic moments were calculated by µ eff = 2.828(χ M × T) 1/2 .…”

Copper–halide bonds as magnetic tunnels; structural, magnetic and theoretical studies of trans-bis(2,5-dibromopyridine)dihalo copper(ii) and trans-bis(2-bromopyridine)dibromo copper(ii)

“…27 In [CuBr 4 22 ] species, the J value is usually weaker than 240 K, with few examples of stronger exchange interactions known. For example, the strongest reported interaction is in catena-ethylenediammonium tetrabromocuprate with J = 2136.8 K, 40,41 this exchange is associated with an extremely short inter-bromide distance, 3.6 Å, and a Cu-Br … Br angle = 157.7u. The number of known examples of two-halide exchange of coordination sphere CuL 2 X 2 is smaller.…”

Synthesis and Structural Investigations of Layered Perovskite System: [NH3-(CH2)3-COOH]2MCL4 ( M= Cd, Hg)

“…However, the most common structure is the perovskite-like structure [1]. A wide variety of different organic and inorganic starting compounds are successfully incorporated in this type of organic-inorganic hybrids perovskites and have been used in many research and practical fields such as thermal energy storage (the advantage of remaining solid after the phase change) [2][3][4][5][6]. Now that certified energy conversion efficiencies for solar cells based on mixed organicinorganic are above 20% [7][8][9].…”
