Oxidative-addition reactions of molecular diiodine and dibromine to divalent organotin compounds. Crystal structures of bis[8-(dimethylamino)-1-naphthyl]tin(IV) dibromide and {2,6-[bis(dimethylamino)methyl]phenyl}- (4-tolyl)tin(IV) diodide

Structure and properties of double-C,N-chelated tri- and diorganotin(IV) halides

“…The molecular structures of 2 and 4 reveal some very close similarities to the previously described 20 and quinolinesubstituted dialkyltin dihalides. 21 The main deviations from the ideal octahedral geometry are the C-Sn-C (152.47 (7) • for 2 and 157.97 (11) • for 4; ideal 180…”

Heteroleptic Organostannylenes and an Organoplumbylene Bearing Phosphorus‐Containing Pincer‐Type Ligands – Structural Variations and Insights into the Configurational Stability

“…Among the class of low‐valent tin compounds heteroleptic organostannylenes of type R Sn X ( R = organic substituent with or without donor functionality, X = F, Cl, Br, I, N(SiMe 3 ) 2 , SC(S)C 6 H 2 ‐ t Bu 3 ‐2,4,6, Si(SiMe 3 ) 3 , Sn(SiMe 3 ) 3 ) have attracted increasing interest over the last two decades 1. Compounds of this type are used for the synthesis of novel unsymmetrically substituted diorganostannylenes of type RR ′Sn [1b,s] as well as of organotin(IV) compounds of type RR ′Sn XY ( R ′ = organic substituent; Y = halogen) 2. Moreover, they are precursors for the syntheses of organotin(I) compounds, R SnSn R ,3 the formal tin analogues of alkynes, and of compounds such as R SnW(P R 3 ) 4 Cl4 and R Sn M (Cp)(CO) 3 ( M = Cr, Mo, W)5 with the former containing a formal tin–transition metal triple bond.…”

Diorganotin(IV) compounds containing 2-(Et2NCH2)C6H4 moieties: Configurational stability in solution and solid state structures

“…Several diorganotin(IV) dihalides containing pendant arm ligands with nitrogen as donor atom, such as 2-(Me 2 NCH 2 )C 6 H 4 [1][2][3][4][5][6][7][8][9] or related organic compounds [1,3,[10][11][12][13][14][15], have been investigated so far both in solution and in the solid state. For all [2-(Me 2 NCH 2 )C 6 H 4 ] 2 SnX 2 (X = halogen) both nitrogen atoms of a molecular unit are strongly coordinated to the metal atom resulting in octahedral cis-X 2 -cis-N 2 -trans-C 2 Sn configurations.…”
