Taming Tin(IV) Polyazides

“…Comparison of thermal properties of compounds 2, 3, 4 and 5 with the lighter Group14h omologues. [a] Compound [33] and [SnCl 4 (phen)]: 2.237(3) , [34] leads to as hortening of the SnÀN(L 2 )b onds by about 2pma nd this reveals the weaker s-electron donor capabilities of N 3 ligands, which is in line with conclusions drawn from the NMR spectroscopic data(vide supra). [47] With the SnÀN a bonds of the neutralm ixed-ligand polyazides 2 to 4 falling within the 2.090(2) to 2.120(2) l ength range, it is the homoleptic,negatively charged hexa(azido)stannate 5 that has significantly longerb onds 2.122(2)-2.147(3) .…”

Structural insights into the coordination chemistry and reactivity of a 3,3′-bis-imine-2,2′-bipyridine ligand

“…The axial Sn-Cl distances [2.4021IJ15) and 2.4316( 16) Å for SnIJ1)-ClIJ2) and SnIJ1)-ClIJ3)] are slightly longer than the equatorial distances [2.3721IJ17) and 2.3771(15) Å for SnIJ1)-ClIJ5) and SnIJ1)-ClIJ4)] and are in agreement with the SnIJIV)-Cl distances for the previously reported six coordinate [SnCl 4 IJphen)] complex. 17 Thus we conclude that during the coordination chemistry reaction, the SnIJII) has been oxidized up to a SnIJIV) cation. Molecules of 1 pack in a head-to-tail arrangement of dimers related by an inversion center that are organized into stacks that pack in a herringbone arrangement, Fig.…”

Tetrachlorido(1,10-phenanthroline-κ2N,N′)tin(IV) 1,2-dichloroethane hemisolvate

“…The contraction of N11-Sn1-N21 to 74.7 (1) from the ideal 90° is typical for a chelating phenanthroline ligand. Figure 2 depicts the π-π interaction between adjacent aromatic rings, which seems, among Cl•••Cl van der Waals contacts, to be significant in the stabilization of the crystal packing, as both preliminary structure determinations of the same complex, either without cocrystallized solvent (Su et al, 2007) or with co-crystallized benzene (Hall & Tiekink, 1996) show the same intermolecular contact features.…”

“…For 1:1 complexes of the type [SnX 4 (NN)] (X = halide; NN = 1,10-phenanthroline or 2,2 0bipyridyl ligand), see: Matsubayashi & Iyoda (1977). For the structure of the title complex without the co-crystallized solvent, see: Su et al (2007) and with co-crystallized benzene, see: Hall & Tiekink (1996). For the preparation of trans-[PtClMe 2 (CH 2 Cl)(phen)] used in the synthesis, see: Monaghan & Puddephatt (1985).…”
