Pentacarbonylhydridorhenium is a chemical compound with the formula ReH(CO)5. This colorless liquid is a weak acid that represents one of the most important derivatives of Re2(CO)10. It is synthesized by treating a methanolic solution of Re(CO)5Br with zinc and acetic acid. [1]

Re(CO)5Br + Zn + HO2CCH3 → ReH(CO)5 Zn(Br)O2CCH3)


It shows moderate sensitivity to light, turning yellow with formation of the cluster Re3H(CO)14

3 Re(CO)5H → Re3H(CO)14 + H2 + CO

At 100 °C, it decomposes to Re2(CO)10:

2 Re(CO)5H → H2 + Re2(CO)10 [2]
