摘要：

The crystal structure of the diamagnetic tris(cyclopentadienyl)technetium(III) (1) has been solved by single crystal X-ray diffraction. The compound crystallizes in the orthorhombic space group Pna2(1) with cell parameters a 1147.7(1), b 904.2(2), and c 1147.2(4) pm; rho-calc 1.636 Mg/m3 for Z = 4. Two rings are pi-bonded and the third one is sigma-bonded. The charge distribution in the molecule and the effective electric charge of the sigma-bonded carbon atom are discussed in comparison to the homologous compounds of vanadium and rhenium.
