Abstract

The use of a ligand directed strategy in the assembly of discrete clusters, 1D chains, 2D layers, and 3D networks using aliphatic N-donor ligands has been investigated. The ligands are a family of amines with rigid backbones [<I>cis,cis</I>-1,3,5-triaminocyclohexane (<I>cis</I>-tach), <I>cis,trans</I>-1,3,5-triaminocyclohexane (<I>trans</I>-tach), <I>cis</I>-1,3-diaminocyclohexane (<I>cis</I>-dach), and <I>cis</I>-3,5-diaminopiperidine (<I>cis</I>-dapi)], and their complexation with Ag(I) salts results in a diverse set of architectures with the following compositions: [Ag<SUB>3</SUB>(<I>cis</I>-tach)<SUB>2</SUB>]F<SUB>3</SUB>·4CH<SUB>3</SUB>OH·0.5H<SUB>2</SUB>O (<B>1</B>), [Ag<SUB>3</SUB>(<I>cis</I>-tach)<SUB>2</SUB>]F<SUB>3</SUB>·6H<SUB>2</SUB>O (<B>2</B>), {[Ag(<I>cis</I>-dach)]ClO<SUB>4</SUB>}<I><SUB>n</SUB></I><SUB></SUB> (<B>3</B>), {[Ag(<I>cis</I>-tach)]NO<SUB>3</SUB>}<I><SUB>n</SUB></I><SUB></SUB> (<B>4</B>), {[Ag(<I>trans</I>-tach)]PF<SUB>6</SUB>}<I><SUB>n</SUB></I><SUB></SUB> (<B>5</B>), and {[Ag(<I>cis</I>-dapi)]CF<SUB>3</SUB>SO<SUB>3</SUB>}<I><SUB>n</SUB></I><SUB></SUB> (<B>6</B>). Structural analysis shows that compounds <B>1</B> and <B>2</B> are discrete M<SUB>3</SUB>L<SUB>2</SUB> cage-type clusters with varying solvent molecule content. Short Ag···Ag contacts (3.021(8) Å) are observed to dimerize discrete units in compound <B>2</B>. Compound <B>3</B> is a 1D zigzag chain formed by coordination to the two primary amines of <I>cis</I>-dach, whereas the tridentate ligands in compounds <B>4</B> and <B>5</B> (<I>cis</I>-tach and <I>trans</I>-tach, respectively) are able to form tubular architectures by virtue of their ability to "wrap" round the channel walls. An infinite 2D coordination network is demonstrated by compound <B>6</B>, in which the three coplanar amino donors of <I>cis</I>-dapi coordinate to the trigonal planar Ag(I) ions to form a layered structure of 6<SUP>3</SUP> topology. These are compared with a previously reported 3D structure, {[Ag(<I>trans</I>-tach)]NO<SUB>3</SUB>}<I><SUB>n</SUB></I><SUB></SUB> (<B>7</B>), that belongs to this family of architectures.
