According to single crystal X-ray diffraction the compound adopts a slightly distorted square planar structure. The empty 4d, 3s and two 4p orbitals undergo dsp2 hybridization to make bonds with CN- ligands in square planar geometry. The dsp2 hybridization favours a planar geometry in which the four hybridized orbitals lie in the equatorial xy plane, as in ICl4- or XeF4. In analyzing the bonding, it is a complex of Rh(I), a d 8 transition metal ion. and square planer respectively . View Square-planar molecules dsp2 hybridization.docx from CHEMISTRY 101 at Colorado School of Mines. The CO ligands will be opposite each other. Option 3),square planar. Whereas there is only one unpaired electron in Cu2+ and hence CuSO4.5H2O shows lowest degree of paramagnetism. The geometry is prevalent for transition metal complexes with d 8 configuration. dsp2 - square planar - wherein. * In [Ni(CN)4]2-, there is Ni2+ ion for which the electronic configuration in the valence shell is 3d8 4s0. As for sp2 hybridization, it is an attempt to explain trigonal planar electron pair geometry where the electron pairs are approximation 120 degrees apart. c) Ni(CO)4 and [Ni(CN)4]2- are diamagnetic; and NiCl42- is paramagnetic. (iii) Ni(CO) 4 has spb3 hybridization, tetrahedral shape, whereas [Ni(CN) 4]2- has dsp2 hybridization, therefore, it has a square planar shape.
