Synthesis,crystal structure,spectroscopic and thermal investigation of trans-diazido- tetrakis(pyrazole)manganese(II) and trans- diaquadiazidobis(3,4-dimethylpyridine)manganese(II)

Two mixed ligand MnII complexes, namely trans- diazidotetrakis(pyrazole)manganese(II) (1) and trans-diaquadiazidobis(3,4-dimethylpyridine)manganese(II) (2) have been synthesized and characterized by spectroscopic and crystallographic methods. The i.r. and Raman spectra are reported and correlated with the structures of both complexes. The e.s.r. spectra of the solid complexes and their solutions are reported. Both complexes are monomeric, with distorted octahedral coordination and terminal azide. The thermal decomposition of both complexes was investigated derivatographically.
