Bis(-2-pyridine-2,6-dicarboxylato)bis[aquadimethyltin(IV)]

M. Yang, R. Zhang and Y. Sun

Abstract: The title dinuclear complex, [Sn₂(CH₃)₄(C₇H₃NO₄)₂(H₂O)₂], lies on a crystallographic inversion center. The unique Sn^IV atom is coordinated in a slightly disorted pentagonal-bipyramidal geometry. The two symmetry-related Sn^IV atoms are connected via two asymmetric Sn-O-Sn bridges (Sn-O = 2.473 and 2.634 Å), such that an exactly planar Sn-O-Sn-O ring is formed.
