title: Bis(diethyl-amido-κN)(diethyl-amine-κN)bis-(2,6-diisopropyl-phenyl-amido-κN)zirconium(IV).
abstract: In the title compound, [Zr(C(12)H(18)N)(2)(C(4)H(10)N)(2)(C(4)H(11)N)] or [Zr(HNC(6)H(3) (i)Pr(2))(2)(NEt(2))(2)(HNEt(2))], which was obtained by the reaction of Zr(NEt)(4) with (i)Pr(2)C(6)H(3)NH(2), the Zr(IV) atom is in a trigonal-bipiramidal geometry in which the N atoms from two (i)Pr(2)C(6)H(3)NH and one NEt(2) ligand occupy the equatorial positions, and the N atoms of an NEt(2) and an Et(2)NH ligand occupy the apical positions. An intra-molecular N-H⋯N contact occurs. There are two independent molecules in the asymmetric unit.
