Abstract: | In the title compound, Cu(N3)2(C15H26N2)], the chiral alkaloid (−)‐l‐sparteine (Sp) acts as a bidentate ligand, with two azide ligands occupying the remaining coordination sites, forming a distorted CuN4 tetrahedron. The dihedral angle between the NSp—Cu—NSp and Nazide—Cu—Nazide planes is 55.3 (2)°. Principal dimensions include Cu—NSp = 2.011 (6) and 2.025 (5) Å, and Cu—Nazide = 1.939 (6) and 1.934 (7) Å. The mid‐point of the NSp⋯NSp line does not lie exactly in the Nazide—Cu—Nazide plane, but is tilted towards one of the NSp atoms by 0.026 Å. |
