WebMost aquo complexes are mono-nuclear, with the general formula [M(H 2 O) 6] n+, with n = 2 or 3; they have an octahedral structure.The water molecules function as Lewis bases, donating a pair of electrons to the metal ion and forming a dative covalent bond with it.Typical examples are listed in the following table. WebFor the low-spin complex [Co (en) (NH3)Cl2]ClO4, identify the following: (a) the coordination number of cobalt. (b) the coordination geometry for cobalt. (c) the oxidation number of cobalt. (d) the number of unpaired electrons. (e) whether the complex is diamagnetic or paramagnetic. arrow_forward. diffuser oils makings dogs sick
