摘要：

119mSn Mössbauer data for a series of base-stabilized, intermolecularly associated tin(II) compounds ith O, Cl, P and As atoms bonded to tin are compared with isomer shifts (IS) and quadrupole splittings (QS) of their stannio complex derivatives with Cr, Mo and W carbonyls. Coordination at the tin lone-pair atom decreases IS to ca. 2.1 ± 0.2 mm s-1 and increases the QS. QS values reflect the highly associated nature of the complexes (CO)5MSn(Cl)E(t-Bu)2 (M Cr, W; E P, As) which are bridged through μ-E(t-Bu)2 groups. © 1979.
