Self host–guest network through molecular paneling of para-nitrophenolate: hydrogen-bonded assembly of three tris(5,5′-diamino-2,2-bipyridine)iron complexes in the crystallographic asymmetric unit

Abstract

The second-sphere hydrogen-bonding interaction of one out of three tris(diamino-bipyridine)iron complexes, [Fe¹(DABP)₃]²⁺, in the crystallographic asymmetric unit with nitrophenolate leads to a cavity created by the nitrophenolate panels whose space is filled through self-inclusion of a crystallographically different [Fe²(DABP)₃]²⁺-cation (DABP = 5,5′-diamino-2,2′-bipyridine).
