Bromidobis(1,10-phenanthroline-κ(2) N,N′)copper(II) dicyanamidate
The title compound, [CuBr(C(12)H(8)N(2))(2)][N(CN)(2)], is formed of discrete [CuBr(phen)(2)](+) complex cations and uncoordinated [N(CN)(2)](−) anions (phen is 1,10-phenanthroline). The Cu atom is five-coordinated in a distorted trigonal-bipyramidal geometry by two phen molecules and one bromide l...

Sumario: | The title compound, [CuBr(C(12)H(8)N(2))(2)][N(CN)(2)], is formed of discrete [CuBr(phen)(2)](+) complex cations and uncoordinated [N(CN)(2)](−) anions (phen is 1,10-phenanthroline). The Cu atom is five-coordinated in a distorted trigonal-bipyramidal geometry by two phen molecules and one bromide ligand, which coordinates in the equatorial plane at a distance of 2.5228 (4) Å and lying along with the Cu and the amide N atoms on a twofold rotation axis. The two axial Cu—N distances [1.9926 (15) Å] are slightly shorter than the two equatorial Cu—N bonds [2.0979 (15) Å]. The structure is stabilized by a weak C—H⋯N hydrogen bond, with a cyanide N atom of the dicyanamide ligand as an acceptor, and π–π interactions between nearly parallel phenyl and pyridine rings of two adjacent phen molecules [centroid–centroid distance = 3.589 (1) Å], and between π electrons of the dicyanamide anion and the pyridine ring [N⋯Cg(pyridine) = 3.511 (3) Å; C—N⋯Cg(pyridine) = 80.2 (2)°]. |
