摘要：
A novel 2-pyridylthiozinc-oxide complex, hexakis (2-pyridylthio)tetrazinc monooxide, which can protect a polyolefin against thermal and oxidative deterioration, particularly against deterioration caused by contact with heavy metals, is disclosed. Various processes for the preparation of said complex are also disclosed.
