Abstract

The mol­ecule of the title compound, [Sn4(C4H9)8(C7H6NO2)4O2], lies about an inversion centre and is a tetra­nuclear bis­(tetra­butyl­dicarboxyl­ato­distannoxane) complex containing a planar Sn4O2 core in which two [mu]3-oxide O atoms connect an Sn2O2 ring to two exocyclic Sn atoms. Each Sn atom has a highly distorted octa­hedral coordination. In the mol­ecule, the carboxyl­ate groups of two amino­benzoate ligands bridge the central and exocyclic Sn atoms, while two further amino­benzoate ligands have highly asymmetric bidentate chelation to the exocyclic Sn atoms plus long O...Sn inter­actions with the central Sn atoms. Each Sn atom is also coordinated by two pendant n-butyl ligands, which extend roughly perpendicular to the plane of the Sn4O10 core. Only one of the four unique hydrogen-bond donor sites is involved in a classic N-H...O hydrogen bond, and the resulting supra­molecular hydrogen-bonded structure is an extended two-dimensional network which lies parallel to the (100) plane and consists of a checkerboard pattern of four-connected mol­ecular cores acting as nodes. The amine groups not involved in the hydrogen-bonding inter­actions have significant N-H...[pi] inter­actions with neighbouring amino­benzene rings.
