“…4) shows a discrete pyramidal anion with a short interaction with the imidazolium proton (H⋯F = 2.006(2) Å). The structures of several [SnF 3 ] − salts have been reported, including 26,[30][31][32] all contain trigonal pyramidal anions with longer Sn⋯F contacts (∼2.6-2.8 Å) linking the anions into chains or sheets. The bulky [IDiPPH] + cation in the present structure is the first structurally authenticated example of an isolated [SnF 3 ] − group.…”

Tin(ii) fluoride vs. tin(ii) chloride – a comparison of their coordination chemistry with neutral ligands

Reaction of SnF2 in MeOH with the appropriate neutral N- or O-donor ligands produces [SnF(2,2'-bipy)]2SnF6, [SnF(1,10-phen)]2SnF4 and [SnF2(L)] L = Me3PO, dmso or pyNO). The X-ray structures of [SnF(2,2'-bipy)]2SnF6, [SnF(1,10-phen)]2SnF4 and [SnF2(dmso)], reveal trigonal pyramidal Sn(II) cores with longer fluorine bridges completing distorted 5- or 6-coordination. Attempts to prepare SnF2 adducts with various phosphine or diphosphine ligands in MeCN failed, whilst in CH2Cl2 solution complex reactions involving the solvent occurred. The NHC, 1,3-(2,6-di-isopropylphenyl)imidazol-2-ylidene (IDiPP) and SnF2 produced the imidazolium salt, [IDiPPH]SnF3, the crystal structure of which revealed the first example of a discrete trifluorostannate(II) ion. In contrast, diphosphine complexes of tin(II) chloride formed readily, including [SnCl2{Me2P(CH2)2PMe2}], [SnCl2{o-C6H4(PMe2)2}], [SnCl2{o-C6H4(PPh2)2}] and [(SnCl2)2(μ-Ph2P(CH2)2PPh2)], which were characterised by X-ray crystallography. The structures of [SnCl2{Me2P(CH2)2PMe2}] and [SnCl2{o-C6H4(PMe2)2}] reveal chloride-bridged dimers, but [SnCl2{o-C6H4(PPh2)2}], although also dimeric, has very asymmetric diphosphine coordination best described as κ(1). The structures of [(SnCl2)2(μ-Ph2P(CH2)2PPh2)] and of [SnCl{o-C6H4(AsMe2)2}]SnCl3 reveal trigonal pyramidal cores, but with longer Sn···Cl bridges affording polymeric structures. The synthesis of [SnCl2(R3EO)2] (R = Ph, E = P or As; and R = Me, E = P) are also reported, along with the structure of [SnCl2(Me3PO)2], which contains distorted tetragonal pyramidal Sn(II) coordination. X-ray structures are also reported for [(PMe3)2CH2][SnCl3]2 and [Ph2P(H)(CH2)2P(H)Ph2][SnCl3]2, obtained as by-products from the attempts to synthesise phosphine complexes, as well as [(o-C6H4(PMe2)2CH2]I2. All complexes were characterised by microanalysis, IR and multinuclear NMR spectroscopy ((1)H, (19)F{(1)H}, (31)P{(1)H } and, where solubility allowed, (119)Sn). Comparisons are drawn with corresponding Sn(IV) and Ge(II) complexes.

Dedicated to the memory of Prof. Dr. Jurij V. Bren~i~. AbstractHydroxylammonium tetrafluoridooxidovanadate(V) has been prepared by reaction of (NH 3 OH)Cl and VOF 3 in anhydrous HF solvent and characterised in the solid state by single-crystal X-ray diffraction and Raman spectroscopy. Colourless (NH 3 OH) [VOF 4 ] crystallises in the monoclinic space group P2 1 /n with a = 7.2349(2) Å, b = 5.0351 (2)

“…Especially, the bond lengths and angles in the pure {SnO 3 } environment seem to be linked to the cluster formation as similar values [d(SnÀ O) = 2.126-2.345 Å and < (OÀ SnÀ O) = 71.3°-84.4°] only have been observed in case of the [Sn 3 (OH) 4 ] 2 + cluster ion, [21] whereas in the discrete [Sn(H 2 O) 3 ] 2 + and [Sn(OH) 3 ] À ions deviating values are found [d(Sn-H 2 O) = 2.200 Å, < (H 2 OÀ SnÀ OH 2 ) = 76.9°; [26] d(SnÀ OH) = 2.045-209.9 Å, < (HOÀ Sn-OH) = 84.1°-92.1°]. [27] For X=F the structural parameters of discrete [SnF 3 ] À ions are more consistent with those of 3 especially when considering their dependence from the different counterions [hydrazinium: d(SnÀ F) = 2.053-2.096 Å, < (FÀ SnÀ F) = 82.0°-87.3°; [28] 1,3-bis(2,6-di-isopropylphenyl)-1H-imidazol-3-ium: d(SnÀ F) = 1.999-20.002 Å, < (FÀ SnÀ F) = 89.27°-90.33°; [29] naphthalene-1,5-diammonium: [30] d(SnÀ F) = 2.031-2.121 Å, < (FÀ SnÀ F) = 84.4°-93.8°].…”

Single crystals of the title compound Sn9F13O(OH)3 ⋅ 2H2O, 3, along with those of the oxofluoride Sn4OF6, 2, and the fluorophosphate Sn3(PO4)F3, 1, have been obtained in course of an experiment mimicking the reaction of the tooth paste additive SnF2 with Ca3(PO4)2 as dentin surrogate. All three compounds have been characterized by single crystal X‐ray diffraction. While our data on the crystal structures 1 and 2 confirm previous results but improve bond lengths and angles precision significantly, 3 represents the first example of a basic tin(II) fluoride the structure of which was determined. Its crystal structure consists of bilayers held together through weak secondary Sn⋅⋅⋅F‐bonds while their unsymmetrical, protic‐aprotic monolayers are connected with each other on their protic sites via −OH⋅⋅⋅F‐hydrogen bonds. The most prominent building block of the monolayers constitutes the unprecedented, stella octangula like [Sn4O(OH)3]3+ cage‐ion. The coordination spheres of all nine Sn(II) atoms are analyzed with respect to their constitution, geometry and bonding. The observed bond lengths and bond angles of the tin(II) atoms are interpretated in terms of p‐p‐bonding via 2e–2c bonds (first coordination sphere, {SnX3}, trigonal‐pyramidal) and 4e–3c‐bonds (second coordination sphere, {SnX4}/{SnX5}, seesaw/square‐pyramidal). Bond valence calculations have been found to be of limited benefit to predict the oxidation state of Sn(II) especially when Sn−O bonds are present.
