چکیده
The structure of the title salt, C(24)H(20)P(+)·H(8)B(3) (-), at 120 (2) K has triclinic (P1) symmetry with an unusual Z = 5, although there is pseudosymmetry observed with the tetraphenylphosphonium cations exhibiting I symmetry. One of the anions is disordered over two sets of sites with refined occupancies of 0.478 (11) and 0.522 (11).

The title compound, (C24H20P)2[CoCl4], was prepared under hydro-thermal conditions. In the crystal, the tetra-phenyl-phospho-nium cations are linked by pairs of weak C-H⋯π inter-actions into supra-molecular dimers; the Co(II) cations lie on twofold rotation axes and the tetra-hedral [CoCl4](2-) anions are linked with the tetra-phenyl-phospho-nium cations via weak C-H⋯Cl hydrogen bonds.

In the anion of the title compound, (C24H20P)[Fe3(C7H7Te)(CO)12], each Fe(0) atom is coordinated by four CO ligands and a Te atom, resulting in a trigonal-bipyramidal coordination environment. The Te atom is coordinated by a 4-methyl-phenyl group and the Fe(0) atoms in a distorted tetra-hedral geometry. The average Te-Fe bond length is 2.574 (4) Å.
