Three heterometallic supramolecular complexes [Cu2(pn)4(Mo(CN)8)·4H2O] (pn = diaminopropane) ( 1 ), [Cu2(pn)4(W(CN)8)·4H2O] ( 2 ) and [Cu2(1,2‐pn)4(H2O) (W(CN)8)·3H2O] ( 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 μ2 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 [Cu2(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 [Cu2(1,2‐pn)2(W(CN)8)]. |
