Crystal structure of bis­{μ(2)-[(2-imino­cyclo­pentyl­idene)methyl­idene]aza­nido-κ(2) N:N′}bis­[(η(5)-penta­methyl­cyclo­penta­dien­yl)zirconium(IV)] hexane monosolvate

The title compound, [Zr(2)(C(10)H(15))(4)(C(6)H(6)N(2))(2)]·C(6)H(14), was obtained by the stoichiometric reaction of adipo­nitrile with [Zr(C(10)H(15))(2)(η(2)-Me(3)SiC(2)SiMe(3))]. Intra­molecular nitrile–nitrile couplings and deprotonation of the substrate produced the (1-imino-2-enimino)­cyclo­pentane ligand, which functions as a five-membered bridge between the two metal atoms. The Zr(IV) atom exhibits a distorted tetra­hedral coordination sphere defined by two penta­methyl­cyclo­penta­dienyl ligands, by the imino unit of one (1-imino-2-enimino)­cyclo­pentane and by the enimino unit of the second (1-imino-2-enimino)­cyclo­pentane. The cyclo­pentane ring of the ligand shows an envelope conformation. The asymmetric unit contains one half of the complex and one half of the hexane solvent mol­ecule, both being completed by the application of inversion symmetry. One of the penta­methyl­cyclo­penta­dienyl ligands is disordered over two sets of sites with a refined occupancy ratio of 0.8111 (3):0.189 (3). In the crystal, the complex mol­ecules are packed into rods extending along [100], with the solvent mol­ecules located in between. The rods are arranged in a distorted hexa­gonal packing.
