Km. Lo et al., BIS[3-(2-PYRIDYL)-2-THIENYL]DI-P-TOLYLSTANNANE, AN EXAMPLE OF A 6-COORDINATE TETRAORGANOTIN COMPOUND, Journal of crystallographic and spectroscopic research, 23(12), 1993, pp. 933-936
The tin atom is bis[3-(2-pyridyl)-2-thienyl]di-p-tolylstannane is six-
coordinate in a distorted cis-octahedral geometry owing to coordinatio
n by the pyridyl nitrogen atoms (Sn<-N=2.620(5), 2.631(5)Angstrom).
