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.

The syntheses and crystal structures of three cyclo-triphosphazenes, all with fluorinated ar-yloxy side groups that generate different steric characteristics, . hexa-kis-(penta-fluoro-phen-oxy)cyclo-triphosphazene, NP(OCF), , hexa-kis-[4-(tri-fluoro-methyl)-phen-oxy]cyclo-triphosphazene, NP[OCH(CF)], and hexa-kis-[3,5-bis(-tri-fluoro-methyl)-phen-oxy]cyclo-triphosphazene, NP[OCH(CF)] , are reported. Specifically, each phospho-rus atom bears either two penta-fluoro-phen-oxy, 4-tri-fluoro-methyl-phen-oxy, or 3,5-tri-fluoro-methyl-phen-oxy groups.

Experimental charge density studies of hexachloro-cyclo-triphosphazene (1) and the boat conformation of octachloro-cyclo-tetraphosphazene (2 a) were performed to unambiguously describe the origin of the electron delocalization in the P N ring in 1. The obtained results were compared to DFT studies in the solid state and the gas phase. Electron density analysis revealed a highly polarized nature of the P-N bonds and a modular structure of the P N and P N rings, which can be separated into independent Cl PN units with a perfect transferability between the compounds.

In the crystal of the title compound, [Cu(2)Cl(4)(C(50)H(32)N(9)O(8)P(3))(2)], the binuclear mol-ecule is located across an inversion center. Each Cu(2+) cation is coordinated by two pyridine N atoms from symmetry-related 4,4;6,6-bis-(biphenyl-2,2'-diyldi-oxy)-2,2-bis-{2-[5-(pyridin-4-yl)-1,3,4-oxadiazol-2-yl]phen-oxy}cyclo-triphosphazene (L) ligands, a pair of bridging Cl(-) anions and a terminal Cl(-) anion, forming a distorted CuCl(3)N(2) square-pyramidal geometry. Weak intra-molecular C-H⋯O and inter-molecular C-H⋯N inter-actions occur in the crystal.

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.
