Abstract

We report on the synthesis, molecular structure and magnetic properties of two novel coordination polymers: [{Cu^II₄(pic)₂(H₂O)₂(MeOH)}{W^V(CN)₈}₂]·MeOH·4H₂O (1) and [{Mn^II₃(HCOO)₂(H₂O)₄}{Mn^II(H₂O)₃(HCONH₂)}₂{Nb^IV(CN)₈}₂]·4HCONH₂·2H₂O (2). The single-crystal X-ray diffraction analysis of 1 shows that its molecular structure can be interpreted as a cyanido bridged (3,4,7)-connected 2D bilayer built of two different subnets sharing the tungsten centers. The magnetic measurements suggest that the system reveals long-range ferromagnetic ordering between Cu^II and W^V centers below 13.4 K. The molecular structure of (2) reveals a 2D topology of layers built of cyanido and formato bridging ligands. The system reveals ferrimagnetic behavior with a critical temperature at 17.8 K.
