A comparative study of reactions of saccharinate (sac), thiosaccharinate (tsac) and benzisothiozolinate (bit) with trans-[PdCl2(H(2)NBz)(2)] is reported. While in all cases substitution of both chlorides occurs, product types differ for the three closely related ligands. With sodium saccharinate, trans-[Pd(N-sac)(2)(H(2)NBz)(2)] results in which the sac ligands are N-bound. A similar N-bound coordination is observed with sodium benzisothiazolinate, but a crystal structure shows that they adopt a mutual cis arrangement in cis-[Pd(N-bit)(2)(H(2)NBz)(2)]. In contrast, with sodium thiosaccharinate it is proposed that the new ligands adopt an S-bound coordination mode in trans-[Pd(S-tsac)(2)(H(2)NBz)(2)].
