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 Mn-II complexes, namely trans-diazidotetrakis(pyrazole)man ganese(II) (1) and trans-diaquadiazidobis(3,4-dimethylpyridine)manganese(II ) (2) have been synthesized and characterized by spectroscopic and crystall ographic methods. The i.r. and Raman spectra are reported and correlated wi th the structures of both complexes. The e.s.r. spectra of the solid comple xes and their solutions are reported. Both complexes are monomeric, with di storted octahedral coordination and terminal azide. The thermal decompositi on of both complexes was investigated derivatographically.
