Heterometallic compounds BaCr2(OH)(Ac)(Nta)2 • 4H2O (I) and [Fe(L)3][Cr2(OH)(Ac)(Nta) 2] • nH2O (L is Bipy (II) and Phen (III); Bipy is, αα′-bipyridine, Phen is o,o′-phenanthroline, Ac - is acetate ion, Nta is nitrilotriacetate ion; n = 8 (II) and 6.25 (III)) are synthesized. According to the X-ray diffraction data, compounds II and III have ionic structures built of the isolated complex cations [Fe(L) 3]2+, binuclear complex anions [Cr2(OH)(Ac) (Nta)2]2-, and crystallization water molecules. The magnetic properties of compounds II and III in the interval from 2 to 300 K confirm assumptions on the diamagnetic character of [Fe(L)3] 2+ and indicate the antiferromagnetic interaction between the chromium atoms in the dimeric fragment [Cr2(OH)(Ac)(Nta) 2]2-. |
