TL;DR: The first phosphane complexes of the hard Lewis acid SnF4 have been synthesized including trans- [SnF4(PR3)(2)] (R = Me or Cy) and cis-[SnF 4(diphosphane)][diphphosphane = R2P(CH2)(2)-PR2, R = Me, Et, Ph or Cy; o-C6H4(PMe2), R = R or Ph] and characterised by IR and multinuclear NMR (H-1, F-19, (31

TL;DR: The pseudooctahedral complexes [SnF4L2] (L = Ph3PO, Ph3AsO, Me 3PO, Me3AsAsO) and [snF4(L-L)] (L −L) as mentioned in this paper have been characterised by analysis, IR, H-1, P-31{H-1} and Sn-119 NMR spectroscopy as appropriate; the NMR studies showing that the complexes of the monodentate ligands exist as mixtures of trans and cis isomers in solution.

TL;DR: The first phosphane complexes of germanium(iv) fluoride with arsane ligands are very unstable and have not been isolated in a pure state and the apparently contradictory literature on the reaction of GeCl(4) with phosphanes is clarified.

TL;DR: In this article, the six-coordinate adducts cis-[GeX4(L-L)] and trans-[GeI4(py)2] were characterised by IR and VT 1H and 19F{1H} NMR spectroscopy.

TL;DR: The first series of phosphane oxide complexes of germanium(IV) halides have been prepared, including trans-[GeF4(R3PO)2] (R = Me, Et or Ph), trans]-GeCl4(Et3PO), fac-[GeCl3(Me 3PO)3]2[GeCl6] and cis]-GeX2(Me3PO4]X2 (X = Cl, Br) as mentioned in this paper.
