The structure and conformation of the complex [BaL](ClO4)(2). MeCN have bee
n studied by NMR spectra and molecular dynamics method in CD3CN solution. T
he coordination geometry of barium(II) is distorted, tricapped trigonal pri
sm. in which the six nitrogen atoms of the imine compose the prism and thre
e pyridyl nitrogen atoms are capping atoms forming nine coordinated structu
