Tuning the dimensionality of H bonded networks using different chalcogen atoms in [Re6Q8(CN)6]4– (Q = S, Se) clusters

Abstract

Two novel compounds based on [Re6Q8(CN)6]4– (Q = S, Se) and small H bond donor bis-amidinium dication of 2,2’-methylenediimidazolium (Cat) (Cat)2[Re6S8(CN)6]∙2H2O (1) and (Cat)2[Re6Se8(CN)6]∙2H2O (2) were synthesized and structurally characterized. Depending of the chalcogen atom (S or Se) in the cluster anion, the dimensionality of the obtained (2D and 3D) network and the nature of the H bond pattern change.
