Crystal structure of (μ-trans-1,2-bis{2-[(2-oxidophenyl)methylidene]hydrazin-1-ylidene}ethane-1,2-diolato-κ3 O,O′,N)bis[di-tert-butyltin(IV)]

The binuclear complex, [Sn 2 (C 4 H 9 ) 4 (C 16 H 10 N 4 O 4 )], contains two Sn 4+ ions, connected by doubly N-deprotonated oxalylbis[(2-oxidobenzylidene)hydrazide] ligands, and each Sn 4+ ion is linked to two tert -butyl groups. The coordination sphere of each Sn atom is best described as a distorted trigonal bipyramid. Each stannic ion in the complex is in a C 2 O 2 N environment. The two homologous parts of the doubly deprotonated ligand are...
