| Abstract
| - The synthesis, structural characterization, and magnetic behavior of a new 2D copper(II) compound with formula {[Cu2(μ-O2CMe)(μ-MedapO)(μ1,1-N3)2]n(CH3OH)n} 1, in which MedapOH is N-methyl-1,3-diamino-2-propanol is reported herein. 1 crystallizes in the triclinic system, space group P1̅, with unit cell parameters a = 6.688(5) Å, b = 10.591(6) Å, c = 12.100(7) Å, α = 113.01(3)°, β = 105.08(4)°, γ = 93.93(3)°, Z = 2. The structure of 1 consists of neutral alternate 1D chains formed by the sequence of [Cu(1)−(μ1,1-N3)2−Cu(1)−(MedapO/acetate)−Cu(2)−(μ1,1-N3)2−Cu2)]. Each dinuclear [Cu(1)−Cu(2)] unit interacts with similar dinuclear units of neighbor chains in basis to large Cu−N(azido) distances to give a 2D arrangement. The magnetic behavior of 1 has been checked giving a net ferromagnetic coupling. The fit of the χM versus T data as dinuclear compound affords a J value of 53.0 cm−1 as a consequence of the orbital countercomplementarity phenomenon. The exchange pathways have been justified by density functional calculations.
- The structural and magnetic study of the new ferromagnetic 2D compound {[Cu2(μ-O2CMe)(μ-MedapO)(μ1,1-N3)2]n(CH3OH)n} prepared by reacting the N-methyl-1,3-diamino-2-propanol and azide ligands with copper(II) is reported. The DFT calculations confirm and illustrate the origin of the ferromagnetic behavior shown by the compound.
