Abstract
A hybrid compound [Mn(2,2'-bipy)3]2[β-Mo8O26]·4H2O prepared by the hydrothermal method consists of a [β-Mo8O26]4- isopolyanion, two isolated manganese-bipyridyl units [Mn(2,2'-bipy)3]2+ and four crystal water molecules. Each [Mn(2,2'-bipy)3]2+ is defined by six nitrogen atoms from three 2,2'-bipyridine molecules forming a distorted MnN6 octahedron. Crystallographic data for the title compound: monoclinic, space group P21/c, a = 12.156(2), b =13.738(3), c = 21.949(4) (A), β = 90.44(3)°, V = 3665.3(13) (A)3, Mr = 2302.57, Z = 2, Dc = 2.086g/cm3, F(000) = 2252, T = 293(2) K, μ(Mo-Ka) = 1.745 mm-1, R = 0.0436, wR = 0.1056, and GOF = 1.074 for 550 parameters and 5515 observed reflections with I ＞ 2σ(I).
