Popis:	A series of (4-FC6H4)3SnML n compounds containing tin-transition metal bonds were synthesized. Based on19F NMR data for these compounds, (4-FC6H4)3SnSn(C6H4F-4)3, and (4-FC6H4)3SnH, conclusions were drawn concerning the polarization direction and relative polarity of the tin-hydrogen and tin-metal bonds in the above compounds and in the hydrides L n MH and R3SnH. It was found that, in the general case, the group electronegativities of the L n M groups do not vary similarly to the electronegativities of the central metal atoms.
