Cyanide-bridged bimetallic 3D Hoffman-like coordination polymers with tunable magnetic behaviour

Abstract

Three cyanide-bridged bimetallic coordination polymers [Fe(bpmp){Ag(CN)2}2]·0.5DMF·0.5EtOH·2H2O (1), [Fe(bpmp){Au(CN)2}2]·DMF·0.5EtOH·H2O (2) and [Fe(bpmp){Ni(CN)4}] (3) (bpmp = 1,4-bis(pyridin-4-ylmethyl)piperazine), have been synthesized and characterized. Single crystal X-ray analysis shows that 1 and 2 are isostructural with a 3D doubly interpenetrated Hoffman-like network without metallophilic interactions, whereas 3 shows a 3D pronouncedly distorted Hoffman framework. Magnetic susceptibility measurements exhibit two-step spin transition properties in 1 and 2, whereas a characteristic paramagnetic behaviour in 3, respectively.
