Synthese, Crystal Structure of O-P-O Bridged Mn<sup>III</sup>(Schiff Base) Phosphinate Complexe

Abstract

A novel O-P-O bridged [Mn (3-MeOsalen)·H2O] (3-MeOsalen = N,N'-ethylenebis (3-methoxysalicylideneiminato) dianion) chain compound, namely [Mn2(3-MeOsalen)2(O2PPh2)(H2O)2] [Mn (3-MeOsalen)(H2O)2]·(ClO4)2·(H2O)4 (1) is successfully synthesized and structurally characterized. Compound 1 crystallized in monoclinic, space group P21/c. This compound consists of two fragments, the dinuclear cationic unit [Mn2(3-MeOsalen)2(O2PPh2)(H2O)2]+, which is resulted from O-P-O bridged cationic unit [Mn (3-MeOsalen)·H2O]+, and mononuclear unit [Mn (3-MeOsalen)(H2O)2]+, forming an one-dimensional chain by intermolecular hydrogen bonding and strong π-π stacking.
