Signs of quadrupole coupling constants for the tin(IV) adducts with acetonitrile, triethylphosphine, and triethylarsine
Abstract
The signs of the quadrupole coupling constants are positive for cis-SnCl4,2MeCN, trans-SnCl4,2PEt3, and trans-SnCl4,2AsEt3 and this is consistent with the order of bond polarity Sn–N (sp-hybridized) > Sn–Cl > Sn–P or Sn–As.
