Two new binuclear complexes, [Mn2(μ-dmpo)2(SCN)4(H2O)2] (1) (where dmpo = 3,5-dimethylpyridine N-oxide), [Mn2(μ-po)2(H2O)6I2]I2 (2) (where po = pyridine N-oxide), have been synthesized and their crystal structures determined by X-ray crystallography. Complexes 1 and 2 crystallize in monoclinic, space group P21/c, with unit cell dimensions a = 8.8836(18) Å, b = 15.450(3) Å, c = 15.484(3) Å, β = 91.020(3)° for 1, and a = 8.8352(13) Å, b = 17.927(3) Å, c = 8.3338(12) Å, β = 103.765(2)° for 2. In each binuclear complex two Mn(II) were bridged by two 3,5-dimethylpyridine N-oxides or by two pyridine N-oxides and the distances between the bridged Mn(II) ions are 3.599 Å for 1 and 3.552 Å for 2. Variable temperature (4-300 K) magnetic measurements were performed for 1 and the susceptibility data were fitted by using a binuclear Mn(II) magnetic coupling formula producing the 2J = -2.17 cm-1. |
