Bis(?(2)-4-amino-3-nitro-benzoato)bis-(4-amino-3-nitro-benzoato)octa-butyldi-?(3)-oxido-tetra-tin(IV).


ABSTRACT: The tetranuclear molecules of the title compound, [Sn(4)(C(4)H(9))(8)(C(7)H(5)N(2)O(4))(4)O(2)], reside on a crystallographic inversion center. Both the two independent Sn atoms are five-coordinate, with distorted trigonal-bipyramidal geometries. One Sn atom is coordinated by two O atoms of the carboxyl-ate anions, one bridging O atom and two butyl groups and the other Sn atom is coordinated by an O atom of the carboxyl-ate anion, two bridging O atoms and two butyl groups. All the butyl groups are equatorial with respect to the SnO(3) trigonal plane. The mol-ecular structure is stabilized by intra-molecular N-H?O hydrogen bonds. In the crystal, pairs of inter-molecular bifurcated acceptor N-H?O and C-H?O hydrogen bonds link the mol-ecules into chains along [10]. Weak inter-molecular C-H?? and ?-? inter-actions [centroid-centroid distance = 3.713?(2)?Å] are also observed.
