Description
Summary:The in situ synthesis of the complex, (PPh^sub 4^)[Mo(CN)^sub 3^O(aceen)] (aceen = N-[1-(pyridin-2-yl)ethylidene]ethane-1,2-diamine), with a 'half unit' Schiff base ligand (with a free amino group) is described and compared with that of [Mo(CN)^sub 2^O(diaceen)]·H^sub 2^O (diaceen = N,N'-bis[1-(pyridin-2-yl)ethylidene]ethane-1,2-diamine) in which a 'classical', tetradentate Schiff base ligand is formed. The mechanism of the 'half unit' and 'classical' template Schiff bases ligand formation is discussed.[PUBLICATION ABSTRACT]
