Crystal structure of (μ-trans-1,2-bis­{2-[(2-oxido­phen­yl)methyl­idene]hydrazin-1-yl­idene}ethane-1,2-diolato-κ(3) 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 located in trans positions with respect to the C—C bond of the oxalamide group. The oxalamide group exhibits an asymmetric coordination geometry, as seen by the slight difference between the C—O and C—N bond lengths. The three-dimensional network is a multilayer of complex mol­ecules with no strong supramolecular inter­actions.
