Spontaneous Self‐Assembly of a Dinickel(II) Double Helicate Containing a 1, 3‐Benzenediyl Spacer Group

A new type of potentially helical ligand is represented by 1. The twist of the molecule's chain required to form double helical complexes by self-organization occurs at the CC bonds between the arene rings. Ligand 1 forms double helical complexes with Cu+, Ag+, and Ni2+ salts. A crystal structure analysis of the complex [Ni2(OAc)2(lb)2](PF6)2 revealed neither intermetallic interactions nor stacking interactions between almost coplanar rings.
