“…Recently we reported the structures of several polymeric Cu II complexes of the form [Cu(cdm) 2 (L) 2 ]Á2MeOH (L = pyridine, 4-ethylpyridine or 3,5-dimethylpyrazole). 119 The complexes form 1D polymers with a pair of cdm ligands in (N,N 0 ) dinitrile bridging modes between axial and equatorial sites of adjacent metals (Fig. 13b).…”

“…As seen in the previous section, the amide groups have the ability to form an R 2 2 (8) motif when both nitrile arms are coordinated to metal atoms. 119 The methanol-linked dimers between the polymeric chains in [Cu(cdm) 2 (py) 2 ]Á2MeOH have a significant degree of tolerance to the presence of other hydrogen bond donors with both 3,5-dimethylpyrazole and an alcoholsubstituted pyridinyl co-ligand not disturbing the hydrogen bonding motifs.…”

The chemistry of the anions dicyanamide and tricyanomethanide (dca and tcm, respectively) has produced a plethora of discoveries over the past few decades, particularly in relation to transition-metal coordination polymers with magnetic coupling. Over recent years there have been an increasing number of reports of heterofunctionalised cyano-containing anions, typically derivatives of dicyanomethanide. Our own group has been particularly concerned with the amide- and nitroso-functionalised anions carbamoyldicyanomethanide (cdm) and dicyanonitrosomethanide (dcnm), respectively. This feature article examines the fascinating diversity of materials and complexes that can be obtained using small cyano anions, ranging from coordination polymers to heterometallic clusters and hydrogen bonding networks. In particular, we focus on results from our own laboratories in the past few years. The magnetic properties of these materials are briefly discussed.

“…Thus, for example, reaction with Cu II and various monodentate pyridyl co-ligands results in the formation of 1D chains in which the metal atoms are bridged by pairs of cdm ligands coordinating through their nitrile nitrogen atoms. [27] The amide groups then hydrogen bond to amide groups of adjacent cdm anions, and to intercalated methanol molecules, linking the chains into 2D sheets.…”
