Crystsl and Molecular Structure of (C 6 H 5 )SnSAB (SAB = Dianion of 2-Hydroxy-N-(2-hydroxybenzylidene)-aniline) (C 6 H 5 ),SnSAB, C 25 H 19 NO 2 Sn, (SAB = tridentate dianion of 2-hydroxy-N-(2-hydroxybenzylidene)-aniline in Schife base (form) crystallizes in the space group Peab (D ) with a = 11.095(2), b = 24.487(4), c = 14.993(3) and Z = 8. The structure has been solved using 1553 symmetrical independent reflections and applying the heavy atom method; the position of all atoms, except the H atoms has been determined. As interatomic distances have been found: Sn C(C 6 H 5 ):2.125, Sn 0: 2.085(8) resp. 2.103(8) ; mean (C C distances in the: phenyl groups a) at Sn: 1.400 b) in the ligand SAB: 1.397. The atoms N and especially C of the Schiff base bridging group C=N are disordered. The coordination polyhedron around Sn essentially forms a distorted trigonal bipyramidal structure with N and the C(C 6 H 5 ) atoms bonded to Sn in the equatorial plane; CSnC = 121.4(4)°; OSnO = 159.5(3)°. No intermolecular Sn 0 bridges exist like in (CH 3 ) 2 SnSAB.
