Four mixed-ligand complexes of [M(mpa)(phen)] n [M = Cd (1) or Zn (2) and mpa = m-phthalate and phen = 1,10-phenanthroline) and [M 2 (mpa) 2 (2,2Ј-bpy) 2 ] n [M = Zn (3) or Cd (4) and 2,2Ј-bpy = 2,2Ј-bipyridine] have been synthesized and their crystal structures have been established by single-crystal X-ray diffraction. They all consist of one-dimensional ribbons featuring dinuclear units. Both 1 and 2 crystallize isomorphously in the monoclinic space group P2/c and feature

Two coordination polymers [Ag(dach)] n (NO 3 ) n (1) and [Ag(teda)(F 3 CSO 3 )] n (2) (dach ϭ 1,2-diaminocyclohexane, teda ϭ 1,4-diazabicyclo[2.2.2]octane) have been synthesized and characterized by X-ray single crystal analysis and cytotoxicity investigation. Compound 1 has a one-dimensional chain-like structure which is extended by ligand unsupported Ag···Ag interactions, hydrophobic interaction and hydrogen bonds into a three-dimen- Synthesen, Kristallstrukturen und zytotoxische Prüfung von zwei kettenartigen und diamantstrukturartigen Silber(I)-Komplexen2.2]octan) wurden synthetisiert und durch Einkristallröntgenstrukturanalyse sowie zytotoxische Prüfung charakterisiert.

The high cytotoxities of these two compounds imply that they are potential candidates for antitumor agents.Wechselwirkung und Wasserstoffbrückenbindungen zu dreidimensionaler, supramolekularer Anordnung führt, während 2 ein dreidimensionales, diamantstrukturartiges Gerüst mit koordinativen Bindungen hat. Die hohe Zytotoxizität dieser zwei Verbindungen weist sie als mögliche Antitumorreagenzien aus.
