“…We refer again the reader to the numerous reviews written on self-assembled architectures generated from titanium and catechol-based ligands or sulfur analogues, some of them being previously mentioned in § 2.1.1.1 and § 2.2.1. [73,75,195,76,77,85,86,170,[192][193][194] In particular, Caulder and Raymond have thoroughly set out the principles that govern self-assembly processes leading to tetrametallic tetrahedral architectures based on catecholcontaining ligands. [194,195] Thus, such architectures could be obtained via a rational synthetic approach.…”

Keywords: Cyclophanes / Platinum / P ligands / Supramolecular chemistry / Self assembly The synthesis of the 1,3,5-tris[(diphenylphosphoryl)alkyl]-benzenes 7−10 succeeds by reaction of the corresponding 1,3,5-tris(bromoalkyl)benzenes 3−6 with ethyl diphenylphosphinite in an Arbusov-type reaction. Reduction of these phosphane oxides leads to the trifunctional phosphane ligands 11−14. Their potency of self-assembly was examined by the employment of platinum(II) complex fragments. A five-component self-assembly consisting of 3 equiv. of the platinum complex Cl 2 Pt(NCPh) 2 and 2 equiv. of the ligands 11−14 un-

Complex formation of the two tetraamine ligands (2S,3S)-1,2,3,4-tetraaminobutane (threo-tetraaminobutane, ttab) and (2R,3S)-1,2,3,4-tetraaminobutane (erythro-tetraaminobutane, etab) with Co(III), Ni(II), Cu(II), and Pd(II) was investigated in aqueous solution and in the solid state. For Ni(II) and Cu(II), the pH-dependent formation of a variety of species [Mn(II)xLyHz](2x+z)+ was established by potentiometric titrations and UV/Vis spectroscopy. In sufficiently acidic solutions the divalent cations formed a mononuclear complex with the doubly protonated ligand of composition [M(H2L)]4+. An example of such a complex was characterized in the crystal structure of [Pd(H2ttab)Cl2]Cl2.H2O. If the metal cation was present in excess, increase of pH resulted in the formation of dinuclear complexes [M2L]4+. Such a species was found in the crystal structure of [Cu2(ttab)Br4].H2O. Excess ligand, on the other hand, lead to the formation of a series of mononuclear bis-complexes [Mq(HxL)(HyL)](q+x+y)+. The crystal structure of [Co(Hetab)2][ZnCl4]2Cl. H2O with the inert, trivalent Co(III) center served as a model to illustrate the structural features of this class of complexes. By using an approximately equimolar ratio of the ligand and the metal cation, a variety of polymeric aggregates both in dilute aqueous solution and in the solid state were observed. The crystal structure of Cu2(ttab)3Br4, which exhibits a two-dimensional, infinite network, and that of [Ni8(ttab)12]Br16.17.5H2O, which contains discrete chiral [Ni8(ttab)12]16+ cubes with approximate T symmetry, are representative examples of such polymers. The energy of different diastereomeric forms of such complexes with the two tetraamine ligands were analyzed by means of molecular mechanics calculations, and the implications of these calculations for the different structures are discussed.
