The complexes [Ni(ntb)(N3)2]·CH3OH (1) and [Cu(ntb)(SCN)]·3CH3OH (2), where ntb = tris(2-benzimidazolylmethyl)amine, were synthesized and their crystal structures determined. Complex 1 is monoclinic, space group P21/c space group with a = 12.777(4), b = 9.928(3), c = 21.623(7) Å, β = 103.145(6)°. The central Ni(II) ion is coordinated to four nitrogen atoms of ntb and two N [image omitted] ions with slightly distorted octahedral geometry. Complex 2 crystallizes triclinic, space group P [image omitted], with a = 11.11(2), b = 13.18(3), c = 13.52(3) Å, α = 63.97(3), β = 66.32(3), γ = 85.55(3)°. Cu(II) is five-coordinate with an N5 ligand donor set comprising four nitrogen atoms of ntb and a nitrogen-bonded SCN- ion, and adopts distorted square pyramidal geometry. In the complexes, hydrogen bonds and π···π interactions are important in stabilising three-dimensional networks. IR, electronic and ESR spectra are discussed, together with magnetic properties at room temperature. |
