I need help with this question: 1. Six-coordinate CR(3) complexes of the type trans-(CrL4A2)n+, generally have magnetic moments consistent with three unpaired electrons, which suggests occupancy of the d orbitals as shown to the right. In principle, a complex with only one unpaired electron could be generated by a suitable choi
