fac-[NEt4]2[Re(CO)3(Br)3] (100.0 mg, 0.130 mmol) was dissolved in water at pH 2.2. Silver nitrate (66.0 mg, 0.389 mmol) was added to the solution and stirred for 24 h at room temperature. After the reaction mixture was filtered (AgBr), 2,5-pyridine dicarboxylic acid(22.0 mg, 0.133 mmol) was added to the solution and stirred under N2 at room temperature for 48 h. The mixture was filtered and the filtrate (pH 2.5) was dried in vacuo. Yield: 55.4 mg, 94 %. IR (KBr,cm-1): mCO = 1899, 2017, 2043. 1H NMR (CD3COCD3): delta = 7.93 (d,1H, J = 8.1 Hz), 8.58 (dd, 1H, J = 1.8 Hz, 8.1 Hz), 9.47 (s, 1H). 13CNMR (CD3COCD3): delta = 128.7, 132.9, 142.7, 151.6, 154.5, 164.5, 178.0, 195.0, 197.6, 198.1. HPLC: 17.84 min. Anal. Calc. C, 26.43;H, 1.33; N, 3.08. Found: C, 26.45; H, 1.30; N, 3.12%.
