(Acetonitrile)[N,N-bis(3-aminopropyl)-1,3-propanediamine-N,N’,N’’,N’’’]c opper(II) diperchlorate

The structure of the title compound, [Cu(C2H3N)(C9H24N4)](ClO4)(2), consists of (acetonitrile) [tris(3-aminon-propyl)amine-N,N’,N ’’,Ntriple prime]copper(II) cations and perchlorate anions linked by an extensive network of weak N-H ... O and C-H ... O hydrogen bonds. The Cu-II atom has a coordination geometry intermediate between tetragonal pyramidal (with one of the three primary amine N atoms occupying the apical coordination site) and trigonal bipyramidal (with the tertiary amine and acetonitrile N atoms in the axial positions). Main dimensions include Cu-N(amine) 2.035(8)-2.121(8) Angstrom and Cu-N(acetonitrile) 2.099(7) Angstrom.
