Abstract

Istražene su mogućnosti funkcionalizacije Andersonovog heteropolioksomolibdata s organskim i metaoloorganskim spojevima. Sintetiziran je simetrično funkconalizirani spoj [N(C4 H9 )4] 3[CoMo6 O18{(OCH2 )3CNH2 }2], a potom njegovom reakcijom s hidrazonskim kompleksom bakra [Cu3 (μ 3 -NO3){(C5 H4N)CH=N–N(C=O)(C5 H4 N)}3 (H2 O)3 ]n(NO3 )2n·3nH2O dobiven je hibrid složene strukture. Koordinacijom aminskih skupina funkcionaliziranog polioksometalata na atome bakra, polianion povezuje dva periferna koordinacijska polimera u jedinstvenu strukturu. Analognom reakcijom s [Cu(NO3 ){(C5 H4 N)2CH=N–NH(C=O)(C5 H4 N)}]2 (NO3 )2 nije bilo moguće prirediti hibrid sličnog sastava. Sljedeći pristup temeljen na reakciji [Cu2(OAc)4 (3-pyCHO)2] s [N(C4 H9 )4]3[CoMo6 O18{(OCH2 )3CNH2 }2] nije doveo do povezivanja dvaju podjedinica već do nastajanja imina. Direktnom reakcijom [N(C4 H9 )4] 3[CoMo6 O18{(OCH2 )3CNH2 }2] s 4-piridinkarbaldehidom priređen je heteropolioksometalat [N(C4 H9 )4]3[CoMo6 O18{(OCH2 )3C=NCHC5 H4 N}2].

Abstract (english)

The functionalization of Anderson-type heteropolyoxomolybdate with organic and metalorganic compounds was investigated. Symmetrically functionalized compound [N(C4 H9 )4] 3[CoMo6 O18{(OCH2 )3CNH2 }2] was prepared, and afterwards, by its reaction with copper hydrazone [Cu3 (μ 3 -NO3){(C5 H4N)CH=N–N(C=O)(C5 H4 N)}3 (H2 O)3 ]n(NO3 )2n·3nH2 O complex, a hybrid with a complex structure was obtained. The polyanion connects the two peripheral coordination polymers into a unique structure by coordinating the amine groups of the functionalized polyoxometalate to the copper atoms. By analogous reaction with [Cu(NO3 ){(C5 H4 N)2CH=N–NH(C=O)(C5 H4 N)}] 2 (NO3 )2, it was not possible to prepare a hybrid with a similar composition. The next approach was based on the reaction of [Cu2(OAc)4 (3-pyCHO)2] with [N(C4 H9 )4] 3[CoMo6 O18{(OCH2 )3CNH2 }2], but this method did not result with the interconnection of the two subunits, but instead the imine formed. The heteropolyoxometalate [N(C4 H9 )4]3[CoMo6 O18{(OCH2 )3C=NCHC5 H4 N}2] was prepared by direct reaction of [N(C4 H9 )4] 3[CoMo6 O18{(OCH2 )3CNH2 }2] with 4-pyridinecarbaldehyde.
