Cyclophosphazene-supported tetranuclear copper assembly containing 15 contiguous inorganic rings
The cyclophosphazene hydrazide gem-N3P3Ph2[N(Me)NH2](4) was reacted with o-hydroxybenzaldehyde to afford the multisite coordination ligand gem-N3P3Ph2[N(Me)N=CHC6H4-2-OH](4) (LH4). The latter reacted with copper(II) salts to afford a novel tetranuclear copper assembly [N3P3Ph2[N(Me)N=CHC6H4-2-O](4)Cu-2}(2), which contains, remarkably, 15 contiguous inorganic rings.
