We have recently reported the synthesis of a series of o-carboranyl methylalcohols bearing pyridine substituents.[1] The presence of two different functionalities (OH and N) in these compounds opens a new door to obtain very attractive carborane based transition metal complexes which could exhibit interesting magnetic, thermal and structural behavior.[2] In this work we explore the coordination chemistry of such compounds and those of related quinolyl derivatives (Figure). Our first results on Co(II) show how the variation of the position of the N atom in the aromatic rings and the inclusion of substitutents, either in the carborane cluster or the nitrogenated rings, give place to the possibility of modulate their molecular interactions which finally lead to different structural characteristics and properties.
