Sažetak
Crystal engineering is a rapidly developing field of structural and supramolecular chemistry. A wide range of assemblies that are relevant to areas ranging from biochemistry to materials science has been conceived and characterized. The main inspiration for this efforts originated in organic solid-state chemistry, but the inorganic solid-state chemistry with its own possibilities and boundaries was quickly recongnized. The most common approach to inorganic crystal engineering has been to propagate the coordination geometry of a specific metal ion into infinite architectures using covalent bonds, leading to coordination polymers of various dimensionality and topology. The plenty of different extended assemblies such as squares, ribbons, grids, helices, interpenetrating or porous networks have been designed. Quickly afterwards, the non-covalent intermolecular interactions were used as additional approach in creating materials with improved solubility and structural flexibility which is inherent in an assemblies built upon hydrogen bonds. Consequently, controlling the properties of a solid through precise control over its crystal structure or principal structural motifs is a demanding task. The reasons for incorporating metal ions into supramolecular networks are numerous: metal ions give access to physical properties that are less common in organic solids such as magnetic properties, conductivity, catalytic activity, metal complexes with hydrogen-bonding capabilities could act as chemotherapeutic compounds etc. A specific geometry of a particular metal ion can be propagated throughout the crystal structure by using attached substituents to the ligands which may act as intermolecular connectors. In order to probe the strength and reliability of various intermolecular connectors, a low dimensional metal-ligand system is convenient starting point, as this may allow us to drive the assembly of linear coordination complexes into one or two dimensions in the crystal lattice via specific intermolecular interactions. Silver(I) is one of the few metal ions that commonly displays linear coordination, thus AgL2 complexes of silver(I) with pyridine derivatives provide the required low-dimensional building units. Particular topics to be addressd include silver(I) complexes with pyridinemono- and dicarboxamides and dihalogenopyridines in designing non-covalent bound supramolecular assemblies.
