Abstract:
In the title compound, [Cu(N(3))(2)(C(15)H(26)N(2))], the chiral alkaloid (-)-l-sparteine (Sp) acts as a bidentate ligand, with two azide ligands occupying the remaining coordination sites, forming a distorted CuN(4) tetrahedron. The dihedral angle between the N(Sp)-Cu-N(Sp) and N(azide)-Cu-N(azide) planes is 55.3 (2) degrees. Principal dimensions include Cu-N(Sp) = 2.011 (6) and 2.025 (5) A, and Cu-N(azide) = 1.939 (6) and 1.934 (7) A. The mid-point of the N(Sp)...N(Sp) line does not lie exactly in the N(azide)-Cu-N(azide) plane, but is tilted towards one of the N(Sp) atoms by 0.026 A.
