Crystal and Molecular Structure of (CH 3 ) 2 SnSAB. (SAB = Dianion of 2-Hydroxy-N-(2-hydroxybenzylidene)-aniline) (CH 3 ) 2 SnSAB, C 15 H 15 NO 2 Sn (SAB = tridentate dianion of 2-hydroxy-N-(2-hydroxybenzylidene)-aniline in S CHIFF base form) crystallizes in the space group Pben (D ) with a = 19.271(5), b = 10.508(2), c = 13.379(1) and Z = 8. The structure has been solved using 1307 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 : 2.117(14), Sn O:2.112(9), Sn N:2.229(11) N C 10 (phenyl group II): 1.462(16), C9-N (S CHIFF base bridging group): 1.257(18), C 9 C8 (phenyl group I): 1.441(18) ; mean C C distances in the phenyl groups: 1.403(18) . Two molecules at a time have a centre of symmetry and weakly coordinate through two loose Sn O bridges (intermolecular Sn O distance: 2.881(8) ). The individual molecules essentially form a distorted trigonal bipyramid with N and both methyl-C atoms in the equatorial plane; CSnC = 138.52(50)°; OSnO = 158.58(35)°.
