The reaction of [n-Bu2SnO]n with 1,5- naphthalenedisulfonic acid tetrahydrate in a 1:1 stoichiometry followed by reaction with 2,2′-bipyridine-N,N′-dioxide (BPDO-I) afforded a 1D-coordination polymer [n-Bu2Sn(BPDO-I)(1,5-C10H 6(SO3)2)]n (1) where the disulfonate ligand acts as a bridging ligand between two tin centers. An analogous reaction involving [Ph2SnO]n afforded a trihydrated O,O′-chelated diorganotin cation [{Ph2Sn(BPDO-I)(H 2O)3}2+][C10H6(SO 3-)2]·2CH3OH (2·2CH3OH). Utilizing two equivalents of BPDO-I in this reaction resulted in the ionic complex [{Ph2Sn(BPDO-I) 2(H2O)}2+][C10H6(SO 3-)2]·3H2O (3·3H 2O). In 2 and 3 the sulfonate ligands are not present in the coordination sphere of tin. Reaction of [n-Bu2SnO]n and 1,5-naphthalenedisulfonic acid tetrahydrate, followed by reaction with [bis(diphenylphosphoryl)methane (DPPOM)] resulted in the formation of, [{n-Bu2Sn(DPPOM)2(H2O)(1,5-C10H 6(SO3)(SO3-)}]·H 2O (4·H2O). Of the two coordinating groups present in DPPOM, only one PO group is coordinated to the tin atom. The remaining PO motif is free and is involved in intramolecular H-bonding with the tin-bound water molecule. Using [Ph2SnO]n instead of [n-Bu 2SnO]n afforded the ionic complex [{Ph 2Sn(DPPOM)2}2+{1,5-C10H 6(SO3-)2}] (5) where the DPPOM functions as a chelating ligand. The reaction of [n-Bu2SnO] n with 1,5-naphthalenedisulfonic acid tetrahydrate followed by addition of one equivalent of 8-hydroxyquinoline (8-HQ) in presence of triethylamine afforded the neutral dinuclear complex, [(H2O)(8-Q)n- Bu2Sn(μ-1,5-C10H6(SO3) 2)n-Bu2Sn(8-Q)(H2O)] (6) where the two tin atoms are bridged by the disulfonate ligand. Compounds 1-6 are thermally stable as shown by their thermogravimetric analyses.
