摘要
The structure of a 1:2 complex of manganese(II) azide with pyridine has been determined by X-ray crystallography. The crystals are tetragonal and belong to the space group I 4(1)/a, with a = 1551.7(4), c = 1003.1(1) pm and Z = 8. The structure has been refined to R = 0.67 for 1152 observed MoK-alpha diffractometer data. The manganese atom is octahedrally coordinated by six ligand nitrogen atoms at distances of 219.5(5), 221.7(4) and 225.9(3) pm. These octahedra are linked together by the mu(1,3)-azido ligands to form a three dimensional network. The azide groups are almost linear and appear to be symmetrical, the N-N distances being 115.1(6) and 117.0(5) pm. The symmetry of the azido ligands is confirmed by disappearance of the nu(s)N3 mode from the infrared spectrum.
