Abstract

The X‐ray crystal structure and properties of the [Mo(CN)2O(acetam)] · 2.5H2O {acetam = N‐[1‐(pyridin‐2‐yl)‐ethylidene]diethanetriamine} complex are described. The complex was prepared by the in situ reaction of [Mo(CN)4O(H2O)]2−, 2‐acetylpyridine and diethylenetriamine in aqueous solution. The complex is seven coordinated. The Mo atom having a distorted pentagonal bipyramid arrangement with a tetradentate ‘half‐unit’ Schiff base and oxygen ligand in a plane. The properties of the salt, i.r., u.v.–vis. spectra and cyclic voltammetry measurements are described and compared with those of [Mo(CN)2O(diaceen)] · H2O {diaceen = N,N′‐bis[1‐(pyridin‐2‐yl)ethylidene]ethane‐1,2‐diamine) having the same coordination number for the metal.
