Transition metal salts of quinoline: synthesis, structure and magnetic behavior of (QuinH)₂[MX₄]·2H₂O [Quin = quinoline; M = Mn, Co, Cu, Zn], (QuinH)₂[MnBr₂(H₂O)₂](Br)₂and (QuinH)[Cu(Quin)Br₃]

Magnetic order and disorder in a quasi-two-dimensional quantum Heisenberg antiferromagnet with randomized exchange

“…Using the published value of g = 2.15 for the x = 0 material 23 , this gives J(x = 0) = 6.1(1) K, in good agreement with the previous estimate. Assuming a similar g-factor, a value of J(x = 1) = 1.4(1) K is obtained, in good agreement with the value derived from susceptibility measurements 24 and consistent with previous measurements that suggest J Br ≈ 4J Cl for Cu 2+ QHAFs 19 .…”

“…The square lattice case is addressed here through pulsed-field magnetization and muon-spin relaxation (µ + SR) measurements of the series (QuinH (QuinH=Quinolinium, C 9 H 8 N + ) [22][23][24][25] . This combination of techniques is well suited to determining the magnetic ground state of low-dimensional Cu 2+ complexes [26][27][28] .…”

Cobalt and zinc halide complexes of 4-chloro and 4-methylaniline: Syntheses, structures and magnetic behavior

“…16,17,18,19,20,21,22 One ongoing area of research in molecular magnetism has focused on transition metal halide complexes with a variety of Ndonor ligands including substituted pyridines 23,24,25 and pyrimidines, 26,27 among others. We have been particularly interested in these types of complexes and their salts employing heterocyclic ligands such as substituted pyridines, 28,29,30 quinoline, 31,32 and isoquinoline. 33 Aromatic amines, such as aniline, also have significant potential for the preparation of complexes of this type.…”
