Abstract

Functional crystalline materials based on bimetallic cyanido-bridged {[Dy(4-Mephen)(dmf)][M(CN)]}·0.5HO (M = Re, 1; Mo, 2; W, 3; 4-Mephen = 4-methyl-1,10-phenanthroline) helices have been prepared. 1 is the first heterometallic coordination polymer incorporating an unexplored [Re(CN)] ion. Implementation of the Re-based diamagnetic analogue of broadly investigated paramagnetic [Mo(CN)] and [W(CN)] ions into the d-f coordination framework results in yellow photoluminescence originating from F → H f-f electronic transitions of Dy sensitized by 4-Mephen, and field-induced slow magnetic relaxation related to the single-ion anisotropy of the dysprosium(III) complexes. We prove that [Re(CN)] can work as a noninnocent metalloligand in the preparation of emissive 4f-metal-based single-molecule magnets.
