Abstract Crystals of Cl 3 SnCH 2 CH 2 CO 2 Pri-i are orthorhombic, space group P2 1 2 1 2 1 with a 9.638 (6), b 10.004 (7) and c 12.848 (8) Å. The tin atom is five-coordinate with two chlorines and carbon equatorial and the remaining chlorine and the carbonyl oxygen axial, in a distorted trigonal-bipyramidal arrangement:(Sn Cl) ax 2.389 (3), average (Sn Cl) eq 2.320 (2), Sn C 2.142 (9), Sn O 2.337 (5) Å. Apart from the equatorial chlorine and the ...
