  A “directed” approach toward a cationic molecular square containing four isonicotinamidate ligands and (4+2) (en)PtII metal entities

  摘要：

  The use of 4-cyanopyridine (4-CNpy) and 3-cyanopyridine (3-CNpy) as ditopic ligands with 180 degrees and 120 degrees directionalities, respectively, for the construction of molecular architectures with the 90 degrees metal fragments (en)Pt-II and (en)Pd-II in water is hampered by the ease with which these ligands undergo hydrolysis to isonicotinamide (4-C(O)NH(2)py) and nicotinamide (3-C(O)NH(2)py). As described in this article, out of six X-ray structurally characterized complexes (1-6), only a single one (1) reveal coordination of the unchanged ligand (4-CNpy) to (en)Pt-II. Nevertheless also the hydrolysis products are of interest in the context of obtaining discrete metallacyclic compounds: Thus, (en)Pt-II and 4-C(O)NH(2)py form a hexanuclear complex, [PF6 subset of{(en)Pt}(6)(4-C(O)NHpy)(4)](NO3)(7)center dot 10H(2)O (2), in which the anionic isonicotinamidate ligands function as tridentate, bridging ligands to produce a hybrid between a metallasquare and a 2-floor open box. The resulting cation with a +8 charge accommodates a single hexafluorophosphate anion in its interior. Adjacent cations of 2 pack in such a way as to develop Pt-4 chains as typically seen in "platinum blues'' and their [Pt-II](4) precursors. (C) 2011 Elsevier B. V. All rights reserved.
