A hexaicosametallic copper(II) phosphonate.

ABSTRACT

Structure and characterization of [Cu26{2,3,5,6-(Me)4C6H-CH2-PO3}18(µ2-OH)4(µ3-OH)6(µ4-Cl)6(µ-OH2)2(OH2)2(MeCN)4]·6MeCN·15H2O (1) is reported. Complex 1 is the largest discrete molecular homometallic transition metal phosphonate assembly. Remarkably, this gigantic molecular phosphonate has been prepared at room temperature using a normal solution synthetic method.
