Product(s) of analogous reactions under atmospheres of H2 or Ar have not been characterized so far. Cluster 3 is diamagnetic, and the 15N NMR spectrum of 15N-labeled 3 exhibited a signal at –75.4 ppm relative to CH3NO2 in THF-d8 (Supplementary Figure 5). A single-crystal X-ray ...
17,18,19,20. In recent years, a particularly successful strategy to promote strong magnetic coupling between lanthanide centers has been the employment of paramagnetic bridging ligands21,22,23,24,25,26,27,28. Significantly, the diffuse spin orbitals of anionic radical ligands are better able to ...
Based on the crystal field theory, the square planar structure is expected to be a low-spin Ni(ii) complex, which is diamagnetic, while the octahedral or tetragonal pyramidal structure is predicted to be a high-spin Ni(ii) complex, which is paramagnetic.18b Therefore, in MeCN, complex 1,...
10. Consider the molecules NO and and N2t. Use molecular orbital theory to answer the followings: a) Draw their molecular orbital diagram (ignore the 1s electrons). b) What is the bond order of each ion? c) Which is paramagnetic and whic...
