Summary
[Zn(NH3)4](ReO4)2 and [Cd(NH3)4](ReO4)2 have been prepared from M(ReO4)2 and aqueous ammonia. The tetrapyridine compounds [Zn(py)4(ReO4)2] and [Cd(py)4(ReO4)2] have been obtained by reacting M(NO3)2 with aqueous pyridine followed by the addition of HReO4. Pyrolysis of these complexes gives [Zn(NH3)2(ReO4)2], [Cd(NH3)2(ReO4)2], [Zn(py)2(ReO4)2] and [Cd(py)2(ReO4)2] respectively. The kinetics of the decomposition steps: [ML4(ReO4)2] → [ML2(ReO4)2] → M(ReO4)2 have been studied from the t.g.a. curves. I.r. and Raman spectral and x-ray powder diffraction studies indicate that all the pyridine complexes and the two diammine complexes contain coordinated perrhenate, while the two tetrammine complexes contain ionic perrhenate.
