Rings pseudoaromatic

Fourth, metallocycles where the metal fragment forms part of a pseudoaromatic ring which is 7r-bonded to a second transition metal fragment are omitted on the grounds of a metal-metal bond. This group includes metallometallocenes, metalloarenes, ferroles, etc. (44,45). 

Meant are cyclic organic microbicides containing N and S atoms in pseudoaromatic ring systems, e.g. thiazole or isothiazole derivatives.
