Supramolecular Complexes Based on [M(CN) 8 ] 4– (M = Mo, W) and Aliphatic Amine Cu II Tectons

Three heterometallic supramolecular complexes [Cu 2 (pn) 4 (Mo(CN) 8 )·4H 2 O] (pn = diaminopropane) ( 1 ), [Cu 2 (pn) 4 (W(CN) 8 )·4H 2 O] ( 2 ) and [Cu 2 (1,2‐pn) 4 (H 2 O) (W(CN) 8 )·3H 2 O] ( 3 ) have been synthesized and structurally characterized by single‐crystal X‐ray diffraction studies. Complexes 1 – 3 exhibit three different networks. In 1 , the copper(II) ion is pentacoordinate with a distorted square‐pyramidal arrangement and the network is formed by the incorporation of coordinative linkage between the μ 2 bridge of [Mo(CN) 8 ] 4– and copper(II) ions and hydrogen‐bonding interactions. In 2 , the copper(II) ion exhibits a distorted square‐pyramidal arrangement and the network is formed by the hydrogen bonded trinuclear complexesof [Cu 2 (pn) 2 (W(CN) 8 )]. In 3 , the copper(II) ions show twodifferent distorted octahedral arrangements. The network structure of 3 is formed by the hydrogen‐bonded complex chains of [Cu 2 (1,2‐pn) 2 (W(CN) 8 )].
