The cationic complex in the title compound, [Ir(C9H7N2)2(C12H8N2)]PF6, comprises two phenylpyrazole (ppz) cyclometallating ligands and one 1,10-phenanthroline (phen) ancillary ligand. The asymmetric unit consists of one [Ir(ppz)2(phen)]+ cation and one [PF6]− counter-ion. The central IrIII ion is six-coordinated by two N atoms and two C atoms from the two ppz ligands as well as by two N atoms from the phen ligand within a distorted octahedral C2N4 coordination set. In the crystal structure, the [Ir(ppz)2(phen)]+ cations and PF6 − counter-ions are connected with each other through weak intermolecular C—H...F hydrogen bonds. Additional C—H...π interactions between the rings of neighbouring cations consolidate the three-dimensional network. Electron density associated with additional disordered solvent molecules inside cavities of the structure was removed with the SQUEEZE procedure in PLATON [Spek (2015). Acta Cryst. C71, 9–18]. The given chemical formula and other crystal data do not take into account the unknown solvent molecule(s). The title compound has a different space-group symmetry (C2/c) from its solvatomorph (P21/c) comprising 1.5CH2Cl2 solvent molecules per ion pair.

In the title salt, {[Ho(NO3)2(C6H18N3OP)4][AgWS4]}n, the anion forms a W/S/Ag polymeric chain along the a axis. The holmium atom in the cation is coordinated by eight O atoms from two nitrate and four hexa­methyl­phospho­ramide ligands in a distorted square-anti­prismatic geometry. Together with the two nitrate ligands, the complex cation in the title compound is univalent, which leads the anion to be univalent as well. The polymeric anionic chain with W—Ag—W and Ag—W—Ag angles of 161.429 (17) and 153.608 (10) °, respectively, presents a distorted linear configuration. The title complex is isotypic with the corresponding Y, Yb, Eu, Nd, La and Dy analogues.
