Hydrothermal reactions of cadmium precursors with 2, 2′‐bipyridine, fumaric acid or NaN 3 in basified aqueous solutions gave rise to two cadmium complexes [Cd(bipy)(fum)(H 2 O)] n ( 1 ), and [Cd(bipy)( μ 1, 1 ‐N 3 ) 2 ] n ( 2 ) (fum = fumarate dianion), which were characterized by X‐ray crystallography. Complex [Cd(bipy)(fum)(H 2 O)] n ( 1 ) crystallizes in the orthorhombic system, space group Pbca, with a = 9.0488(8), b = 16.246(3), c = 19.810(4) Å, and Z = 8 while complex [Cd(bipy)( μ 1, 1 ‐N 3 ) 2 ] n ( 2 ) in the monoclinic system, space group C2/c, with a = 12.378(3), b = 14.788(3), c = 6.6139(13) Å, β = 91.49(3)°, and Z = 4. The photoluminescence spectra for compounds 1 and 2 have also been studied.
