The differences in solid state structures of C,N-chelated nbutyltin(IV) fluorides
摘要:
The solid state structures of products of. uorination of LCNnBuSnCl2 ( where LCN is 2-[( CH3) 2NCH2] C6H4 -) by different methods are reported. The reaction of 3 equiv. of [ NH4]+[ LCNnBuSnF3] and Pr( OTf) 3 led to dimeric arrangement [ LCNnBuSnF( l- F) 2SnLCNnBuF] 2HOTf. Two different polymorphs of polymeric [ LCNnBuSnF2] n have been obtained by crystallization. Prepared compounds were studied by X- ray crystallographic methods, DSC and theoretical calculations at the B3LYP/ LANL2DZ level. (c) 2008 Published by Elsevier B. V.
