Acta Crystallographica Section E Structure Reports Online (Impact Factor: 0.35). 05/2008; 64(Pt 5):m603-4. DOI: 10.1107/S1600536808008179

The structure of the title compound, [Cu(PTA)(4)]Cl·6H(2)O (PTA is 1,3,5-triaza-7-phosphaadamantane, C(6)H(12)N(3)P), is composed of discrete monomeric [Cu(PTA)(4)](+) cations, chloride anions and uncoordinated water mol-ecules. The Cu(I) atom exhibits tetra-hedral coordination geometry, involving four symmetry-equivalent P-bound PTA ligands. The structure is extended to a regular three-dimensional supra-molecular framework via numerous equivalent O-H⋯N hydrogen bonds between all solvent water mol-ecules (six per cation) and all PTA N atoms, thus simultaneously bridging each [Cu(PTA)(4)](+) cation with 12 neighbouring units in multiple directions. The study also shows that PTA can be a convenient ligand in crystal engineering for the construction of supra-molecular architectures.

    ABSTRACT: The reactions of CoCl2 with the alkylated aminophosphine N-alkyl-1,3,5-triaza-7-phosphaadamantane iodide [PTA-R]I (R=Me, Et) and NaSCN, in an ethanolic medium at ambient temperature, lead to the self-assembly formation of the hybrid 2:1 organic–inorganic salts [PTA-R]2[Co(NCS)4] (R=Me (1); Et (2)), which have been characterized by IR spectroscopy, FAB+-MS, elemental and single crystal X-ray diffraction structural analyses. The molecular structures bear two cage-like [PTA-R]+ cations and one discrete tetrahedral [Co(NCS)4]2− anion. Adjacent anions are linked via repeating weak intermolecular S⋯S contacts forming 1D supramolecular inorganic networks, acting as hosts for the [PTA-R]+ guests. 1 and 2 represent the first structurally characterized examples of compounds where any uncoordinated cage-like PTA derivative acts as a component of a hybrid organic–inorganic material.

    ABSTRACT: The aqueous medium self-assembly reactions of copper(II) nitrate with 1,3,5-triaza-7-phosphaadamantane (PTA) as a main ligand and sodium azide or iodide as an auxiliary ligand lead to the new water-soluble Cu(I) coordination polymer [Cu(μ-N3)(μ-PTA)]n (1) and monomer [CuI(PTA)(PTAH)2]I2·H2O (2) (PTAH = N-protonated form of PTA), with the PTA cages exhibiting the rare P,N- or the conventional P-coordination mode, respectively. Another hydrosoluble P-bound PTA derivative [Cu(PTA)4](NO3)·6H2O (3) is furnished in the absence of any auxiliary ligand. The compounds have been characterized by IR and NMR spectroscopy, elemental and single crystal X-ray diffraction analyses which feature the formation of a unique one-dimensional (1D) coordination network in 1 composed of the {Cu2(μ-N3)2} cores and PTA spacers, as well as 1D (in 2) and three-dimensional (3D) (in 3) supramolecular structures built from multiple N−H···N (PTAH/PTA) and O−H···N (H2O/PTA) H-bonds, respectively. The study broadens the still limited use of PTA as a spacer or building block for crystal engineering of metal−organic coordination and supramolecular networks, their nature being also dependent on the type of auxiliary ligand. Compound 1 represents the first example of a copper coordination polymer with PTA.

    ABSTRACT: New copper(I) complexes containing the water soluble N-methyl-1,3,5-triaza-7-phosphaadamantane (mPTA) phosphine have been synthesized by ligand-exchange reactions starting from [Cu(CH(3)CN)(4)][BF(4)] or [Cu(CH(3)CN)(4)][PF(6)] precursors and (mPTA)X (X=CF(3)SO(3), I). Depending on the ligand counter ion, the hydrophilic [Cu(mPTA)(4)][(CF(3)SO(3))(4)(BF(4))] 3a and [Cu(mPTA)(4)][(CF(3)SO(3))(4)(PF(6))] 3c complexes or the iodine-coordinated [Cu(mPTA)(3)I]I(3)4 species were obtained respectively and fully characterized by spectroscopic methods. Single crystal structural characterization was undertaken for [Cu(mPTA)(3)I]I(3).H(2)O, 4.H(2)O, and [Cu(mPTA)(4)][(CF(3)SO(3))(2)(BF(4))(3)] .0.25H(2)O, 3b.0.25H(2)O, the latter obtained by crystallization of [Cu(mPTA)(4)][(CF(3)SO(3))(4)(BF(4))] 3a. The cytotoxicity of analogous tetrahedral homoleptic Cu(I) derivatives [Cu(PTA)(4)](BF(4)) 1, [Cu(PTAH)(4)][Cl(4)(BF(4))] 2, [Cu(mPTA)(4)][(CF(3)SO(3))(4)(BF(4))] 3a and [Cu(mPTA)(4)][(CF(3)SO(3))(4)(PF(6))] 3c was evaluated against a panel of several human tumor cell lines. All the complexes showed in vitro antitumor activity comparable to that of the reference metallodrug cisplatin. Tests performed on cisplatin sensitive and resistant cell lines showed that against human ovarian 2008/C13(*) cell line pair, the resistance factor of copper derivatives was roughly 7-fold lower than that of cisplatin, whereas against human cervix cancer A431/A431-Pt cell line pair it was about 2.5-fold lower. These results, confirming the circumvention of cisplatin resistance, support the hypothesis that phosphine copper(I) complexes follow different cytotoxic mechanisms than do platinum drugs.
