Unique example of a T3(2)4(2)3(2)6(2) water tape containing acetate–water hybrid hexamer in a heterometallic schiff base complex host

The novel T3(2)4(2)3(2)6(2) tape, constructed by acetate–water hybrid hexamer [(H2O)4(CH3COO)2]2−, water trimers and tetramer, has been observed for the first time in a heterometallic Schiff base complex host, [Cu(vanpn)Na(CH3COO)(H2O)]. 2H2O, {H2vanpn = N,N′-propylene-bis(3-methoxysalicylideneimine}. The present findings provide insight and serve as a prototype for stabilizing other pure and hybrid water clusters.
