μ-2,2,4,4,6,6-Hexakis(3,5-dimethyl-pyrazol-1-yl)-2λ,4λ,6λ-1,3,5,2,4,6-triaza-triphosphinine]bis-[bis-(nitrato- κO,O')cadmium(II).

The complete title complex, [Cd(2)(NO(3))(4)(C(30)H(42)N(15)P(3))], is generated by crystallographic twofold symmetry, with one P and one N atom of the cyclo-triphosphazene ligand located on the rotation axis. The non-planar cyclo-triphosphazene ring accommodates two Cd ions, and only four out of six exocylcic pyrazolyl ligands are bound to the Cd metal atoms. Each of these two symmetry-related Cd atoms is coordinated by two bidentate nitrato ligands, two exocylic pyrazolyl N atoms, and one cyclo-triphosphazene N atom.

μ(3)-2,2,4,4,6,6-Hexakis(3,5-dimethyl-pyrazol-1-yl)-2λ,4λ,6λ-1,3,5,2,4,6-triaza-triphosphinine]tris-[cis-dichloridopalladium(II).

The title complex, [Pd(3)Cl(6)(C(30)H(42)N(15)P(3))], possesses C(3) mol-ecular symmetry. The P and N atoms of the cyclo-triphosphazene and the Pd atom are located on the crystallographic mirror plane. Each of the three symmetry-related Pd atoms is coordinated by two chloride ligands and two exocyclic pyrazolyl N atoms, but not by the cyclo-triphosphazene N atoms.
