New nickel(II) and copper(II) complexes with 1-tert-butyl-1H- and 1,5-diaminotetrazoles

Synthesis, Structure, and Magnetic and Biological Properties of Copper(II) Complexes with 1,3,4-Thiadiazole Derivatives

“…For instance, in the structure of one of these complexes, [Cu2( [31], the Cu-Cu distance within dimers is 7.134(1) Å, while the shortest dimers is 6.752(1) Å. In the [Cu2(medpt)2(C2N3)2](ClO4)2 binuclear com Cu distance is 6.975 Å within dimers and as large as 8.562 Å between the polymer Cu(L2)2(C2N3)2 studied in our earlier work [33], the distances bet connected by cyanamide bridges are 7.30 Å and 7.707 Å.…”

“…In the [Cu 2 (medpt) 2 (C 2 N 3 ) 2 ](ClO 4 ) 2 binuclear complex [ 32 ], the Cu-Cu distance is 6.975 Å within dimers and as large as 8.562 Å between them. In the layered polymer Cu(L 2 ) 2 (C 2 N 3 ) 2 studied in our earlier work [ 33 ], the distances between copper ions connected by cyanamide bridges are 7.30 Å and 7.707 Å.…”

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

“…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.…”
