The 2D and 3D Compounds [M2bpm(dca)4]·nH2O (M = Ni, Zn; bpm = bipyrimidine; dca = dicyanamide; n = 0, 1) − Structural Analysis and Magnetic Properties
2001
The combined use of bpm (2,2′-bipyrimidine) and dca (dicyanamide) has led to the preparation of two compounds of general formula [M2bpm(dca)4]·nH2O. Compound 1 (M = Ni, n = 1) exhibits a 2D layered structure based on ladder-like moieties. These units, whose steps are bpm groups, extend through single dca bridges, the connection between distinct ladder-like units taking place through double dca bridges. Compound 2 (M = Zn, n = 0) consists of a 3D structure based on the same type of ladder-like moieties that are connected to another four on the plane perpendicular to the extension of the ladders.
