Synthesis, structure, and magnetic properties of a family of copper(II) complexes and salts of isoquinoline: (Isoquinoline) Cu(X)2 [X = Cl, Br] and (isoquinolinium)2CuX4(H2O) [X = Cl, Br; n = 0,1]

Constructing π-Stacked Supramolecular Cage Based Hierarchical Self-Assemblies via π···π Stacking and Hydrogen Bonding

“…The Mn@Mn 4 -cage consists of four [Mn­(H 2 O) 4 ] 2+ vertexes and six Br 4 2– edges, with a [Mn­(H 2 O) 6 ] 2+ trapped at the center (Figure S9). The Br 4 2– anions are likely generated by the in situ aerobic oxidation of Br – ions, which has been observed in the formation of Br 3 – during the synthesis of an isoquinolinium salt . Its central and bilateral Br–Br distances are 3.130 and 2.853 Å, respectively, close to those of the reported Br 4 2– anions .…”

Magneto–structural maps and bridged-ligand effect for dichloro-bridged dinuclear copper(ii) complexes: a theoretical perspective

“…In addition, when non-chloride halides are used as bridging ligands, participatory ligand p/d orbitals may convolute magnetic exchange interactions. 20,21,34 Meanwhile, Ruiz et al 11 studied the relationship between the magnetic coupling constant and the structure of dimeric copper complexes bridged by different halogen ligands and ligands using dichloro-bridged binuclear copper model compounds. Their results showed that when the non-bridging ligand atom was a nitrogen atom, the paramagnetic centers tended to ferromagnetically couple.…”

“…4–7 Furthermore, synthetic dinuclear paramagnetic Cu( ii ) chloride complexes that contain {Cu–(μ-Cl) 2 –Cu} fragments have found spintronic, sewage treatment, and magnetic applications. 8–29 While magnetic properties of these complexes feature in their function, analyses of these systems and various synthetic dinuclear Cu( ii ) complexes have yet to establish structure–magnetic relationships. 6,7 Specifically, relationships between exchange interactions between paramagnetic Cu centers, summarized by the magnetic exchange coupling constant ( J ), and structural parameters for these complexes are poorly understood.…”

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

“…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. Aniline and substituted aniline compounds have been examined both for their qualities as Lewis bases 34 and in studies of how their basicity affects reactions and reaction mechanisms in the synthesis of complexes with the formula ML2X2 (X = Cl, Br; L = aniline-based ligand).…”
