Syntheses and magneto-structural study of several polynuclear copper(II) complexes derived from 1,3-bis(dimethylamino)-2-propanolato
The syntheses, structural characterization, and magnetic behavior of the three new polynuclear copper(II) complexes with formulas [Cu-4(eta(2):mu-CH3COO)(2)(mu-OH)(2)(mu-OH2)(mu-bdmap)(2)](ClO4)(2).H2O (1), [Cu-8(NCO)(2)(eta(1):mu-NCO)4(mu-OH)(2)(mu(3)-OH)(2)(mu-OH2)(3) (mu-bdmap)(4)](ClO4)(2).2H(2)O (2), and [Cu-9(eta(1):mu-NCO)(8)(mu(3)-OH)(4)(OH2)(2)(mu-bdmap)(4)](ClO4)(2).4H(2 )O (3), in which bdmapH is 1,3-bis(dimethylamino)-2-propanol, are reported. Tetranuclear complex 1 crystallizes in the triclinic system, space group P1, with unit cell parameters a = 12.160(1) Angstrom, b = 13.051(1) Angstrom, c = 13.235(1) Angstrom, alpha = 110.745(1)degrees, beta = 109.683(1)degrees, gamma = 97.014(1), and Z= 2. Octanuclear complex 2 crystallizes in the monoclinic system, space group C2/c, with unit cell parameters a = 26.609(1) Angstrom, b = 14.496(1) Angstrom, c = 16.652(1) Angstrom, beta = 97.814(1)degrees, and Z = 4, and nonanuclear complex 3 crystallizes in the monoclinic system, space group C2/c, with unit cell parameters a = 24.104(1) Angstrom, b = 13.542(1) Angstrom, c = 24.355(1) Angstrom, beta = 109.98(1)degrees, and Z = 4. The magnetic behavior of the three complexes has been checked showing strong antiferromagnetic coupling in all the cases.
