A di-olato-bridged dinuclear copper(II) compound of the tripodal triamine alcohol bis-2-(3-aminopropyl)-2-aminoethanol

Bis-mu-O-[(bis-2-(3-aminopropyl)-2-aminoethanolato-N,N,O)copper(II)] perchlorate, with the deprotonated tripodal ligand bis-2-(3-aminopropyl)-2-aminoethanol, has centrosymmetrical dinuclear cations. The copper(II) ion is in square pyramidal coordination {Cu-O 1.943(4), Cu-O# 1.962(4)} Cu-N-tertiary 2.050(5) and Cu-N-primary 2-021(4) Angstrom} with the second primary amino group axially coordinated {Cu-N 2.192(6) Angstrom}. The Cu ions of the dinuclear cation are 2.980(2) Angstrom apart, with O-Cu-O# 80.5(2)degrees, Cu-O-Cu# 99.5(2), N-Cu-O 93.5(2), C-O-Cu 110.4(2) and C-O-Cu# 127.3(4)degrees, with the angles about the oxygen atom summing to 319.2(6)degrees.
