Tutkielman kirjallisessa osassa k\u00e4yd\u00e4\u00e4n ensin l\u00e4pi siirtym\u00e4metallien ja lantanoidien ominaisuuksia, lyhyesti supramolekyylikemian perusteita sek\u00e4 metalliorgaanisten verkkorakenteiden (engl. metal-organic framewoks, MOF) rakenteellinen m\u00e4\u00e4ritelm\u00e4. HMOF rakenneosiossa esitell\u00e4\u00e4n eri synteesimenetelmi\u00e4, karakterisointimenetelmi\u00e4 ja lantanoidi siirtym\u00e4metalli systeemien magneettisia ominaisuuksia sek\u00e4 luminesenssia.

Synteesituotteet karakterisoitiin (_^1)H^ NMR spektroskopian ja yksikider\u00f6ntgendiffraktion avulla ja niiden ominaisuuksia sek\u00e4 puhtautta tarkasteltiin termogravimetrian keinoin. \nKompleksoinnit suoritettiin k\u00e4ytt\u00e4en kolmea ligandia, 13 siirtym\u00e4metallisuolaa ja yhdeks\u00e4\u00e4 lantanoidimetallisuolaa. Kiteytysmenetelmin\u00e4 k\u00e4ytettiin ensisijaisesti diffuusio ja haihdutuskiteytyksi\u00e4. N\u00e4iden ohella kokeiltiin muutamia hydrotermisi\u00e4 synteesej\u00e4 ja apuligandikiteytyksi\u00e4. Kompleksoinnit onnistuivat parhaiten 1:2:1 dioksaanidiffuusio ja haihdutuskiteytyksist\u00e4, joissa metallisuolat oli liuotettu etanoliin ja ligandi veteen. Tutkimuksen yhteydess\u00e4 ei syntynyt varsinaisia HMOF rakenteita, mutta yksi heterometallinen Ag,Nd koordinaatiopolymeeri (engl. coordination polymer, CP) kiteytyi.
