Abstract

Istraživanje koordinacijskih polimera, kao i metalo-organskih mreža, značajno se intenziviralo
u posljednih nekoliko godina. Zbog svojih svojstava koordinacijski polimeri su pokazali
izniman potencijal primjene u mnogim područjima ljudske djelatnosti. Najčešće se sastoje od
metalnih iona d- i f-bloka periodnog sustava elemenata koji su premošteni pomoću drugih
molekula tvoreći tako polimere u jednoj, dvije ili tri dimenzije. Ovisno o svome sastavu,
koordinacijski polimeri imaju specifična svojstva. Posebno su zanimljivi kiralni
koordinacijski polimeri sa šupljinama u kristalnoj strukturi i koji se često koriste za
razdvajanje enantiomera ili za “dostavu“ lijekova u slučaju kad su izgrađeni od
biokompatibilnih gradivnih jedinica.
U sklopu ovog rada priređeni su i strukturno karakterizirani koordinacijski polimeri bakra(II),
kobalta(II) i nikla(II) s 1,2-bis(4-piridil)etanom kao premošćujućim ligandom. Sva tri
koordinacijska polimera su izostrukturni (P622) i sadrže nitratne anione za razliku od
poznatog kompleksa bakra(II) s istim ligandom i perkloratnim anionima (P21/n). Razlozi
mogu biti mnogostruki, ali vjerojatno je presudan utjecaj aniona i njegovih svojstava.

Abstract (english)

Research on coordination polymers, as well as metal-organic networks, has intensified
significantly in recent years. Due to their properties, coordination polymers have shown
exceptional application potential in many areas of human activity. They usually consist of
metal ions of the d- and f-blocks of the periodic table of elements that are bridged by other
molecules, thus forming polymers in one, two or three dimensions. Depending on their
composition, coordination polymers may have specific properties. Of particular interest are
chiral coordination polymers with cavities in the crystal structure that are often used to
separate enantiomers or to "deliver" drugs in the case where they are constructed from
biocompatible building blocks.
Coordination polymers of copper(II), cobalt(II) and nickel(II) nitrates were prepared with 1,2-
bis(4-pyridyl)ethane as a bridging ligand. All three complexes with nitrate anion are
isostructural (P622) as opposed to the complex formed from perchlorate anion (P−1). The
reasons can be multiple, but the influence of the anion and its properties is probably crucial.
