Tetra­phenyl­phospho­nium [μ₃-(4-methyl­phen­yl)tellurolato]tris­[tetra­carbonyl­iron(0)]

In the anion of the title compound, (C₂₄H₂₀P)[Fe₃(C₇H₇Te)(CO)₁₂], each Fe⁰ 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-methyl­phenyl group and the Fe⁰ atoms in a distorted tetra­hedral geometry. The average Te—Fe bond length is 2.574 (4) Å.

N,N,N,N′,N′,N′-Hexa­kis­(2-hy­droxy­ethyl)butane-1,4-diaminium bis­(2-sul­fan­ylidene-1,3-di­thiole-4,5-dithiolato-κ²S⁴,S⁵)zincate

In the asymmetric unit of the title compound, (C₁₆H₃₈N₂O₆)[Zn(C₃S₅)₂], two independent cations lie across inversion centers. In one of the cations, the three symmetry-unique O—H groups are disordered over two sets of sites with refined occupancy ratios of 0.701 (9):0.299 (9), 0.671 (8):0.329 (8) and 0.566 (7):0.434 (7). In the anion, the Zn^II ion is coordinated in a distorted tetra­hedral environment by four S atoms of two chelating 1,3-di­thiole-2-thione-4,5-dithiolato ligands. The dihedral angle between the mean planes [maximun deviations = 0.022 (3) and 0.0656 (6) Å] of the two ligands is 87.76 (3)°. An intamolecular O—H...O hydrogen bond occurs in the disordered cation. In the crystal, O—H...O and O—H...S hydrogen bonds link the components into a two-dimensional network parallel to (0-11).

Bis[O,O′-bis­(4-tert-butyl­phen­yl) di­thio­phosphato-κ²S,S′]bis­(pyridine-κN)lead(II)

In the title compound, [Pb(C₂₀H₂₆O₂PS₂)₂(C₅H₅N)₂], the Pb^II ion is coordinated by two S,S′-bidentate anions and two pyridine mol­ecules. The PbN₂S₄ coordination geometry approximates to a penta­gonal bipyramid with one equatorial site vacant. The N atoms occupy the axial sites. One of the pyridine mol­ecules is disordered over two sets of sites in a 0.907 (7):0.093 (7) ratio and one of the tert-butyl groups is disordered over two sets of sites in a 0.534 (6):0.466 (6) ratio. An intra­molecular C—H...O inter­action occurs in one of the ligands. In the crystal, pairs of short Pb...S contacts [3.4018 (11) Å] generate a centrosymmetric dimeric assembly with the distant S atom lying in the region of the vacant coordination site of the metal atom. No directional packing inter­actions occur.
