Triethyl­ammonium O-3β-cholest-5-en-3-yl (4-meth­oxy­phen­yl)dithio­phospho­nate

In the crystal structure of the title compound, C6H16N+·C34H52O2PS2 − or [(CH3CH2)3NH]+·[C34H52O2PS2]−, the cation and anion are paired via weak, inter­molecular, bifurcated N—H⋯(S,S) hydrogen bonds. The cholesteryl units form an alternating (herringbone) motif as well as an infinitely stacked layered structure along the b axis. The P—S bond lengths [1.975 (2) and 1.981 (2) Å compared with ca 1.92 Å for a formal P=S double bond and with ca 2.01 Å for a P—S single bond] suggest delocalization of the negative charge between the P—S bonds. A distorted tetra­hedral geometry around the P atom is revealed by non-ideal O—P—C and S—P—S bond angles of 96.7 (2) and 115.52 (11)°, respectively

(Ferrocenyl­thio­phospho­nato-κS)(triphenyl­phosphane-κP)gold(I) dichloro­methane monosolvate

In the title compound, [AuFe(C5H5)(C5H5O2PS)(C18H15P)]·CH2Cl2, the two-coordinate gold(I) atom shows a slightly distorted linear arrangement, with a P—Au—S bond angle of 176.81 (6)°. The difference in P=O and P—O(H) bond lengths, which are 1.503 (6) and 1.541 (5) Å, respectively, implies there is apparently no delocalization between the P—O bonds, and the proton appears to be localized on one O atom only. In the crystal structure, inter­molecular O—H⋯O hydrogen bonds link dinuclear mol­ecules into chains propagated in the [010] direction. The dichloro­methane solvent mol­ecule was disordered between two positions in a 0.63 (3):0.37 (3) ratio
