摘要：

Steric differences alone explain why 1 has a diamagnetic and 2 a paramagnetic electronic ground state. In 1 the W-O bonds are 0.12 angstrom shorter. which results in a stronger W-O pi bond and therefore a greater splitting of the t2g orbitals, which are degenerate for ideal octahedral symmetry. The bulky ligand in 2 precludes such short W-O bonds. Comparisons with other control compounds show that electronic effects are not a factor. [GRAPHICS]
