    In the title compound, [Cu(ClO4)(C2H3N)(C15H19N3O)]ClO4, the CuII ion is coordinated by three N atoms and a hydroxyl-O atom of the tetra­dentate ligand, an O atom of a perchlorate ion and an N atom of an acetonitrile ligand giving a tetra­gonally distorted octa­hedral environment around the copper(II) atom. There is an offset inter-complex face-to-face π–π inter­action [centroid–centroid distance = 3.718 (2) Å] involving one of the pyridine rings of the ligand as well as an intra-complex O—H⋯O hydrogen-bonding inter­action between the coordinated hydroxyl group of the ligand and the perchlorate counter-ion

    In the title thio­cyanate-coordinated aza-macrocyclic copper(II) complex, [Cu(NCS)2(C24H38N6)], the CuII atom is coordinated by the four secondary N atoms of the aza-macrocyclic ligand and by the two N atoms of the thio­cyanate ions in a tetra­gonally distorted octa­hedral geometry. The average equatorial Cu—N bond length is shorter than the average axial Cu—N bond length [2.010 (2) and 2.528 (4) Å, respectively]. An N—H⋯N hydrogen-bonding inter­action between the secondary amine N atom and the adjacent thio­cyanate ion leads to a polymeric chain along the a axis

    In the title compound, [Cu(N3)2(C20H21N3)], the CuII ion is coordinated by the three N atoms of the (S)-1-phenyl-N,N-bis­[(2-pyrid­yl)meth­yl]ethanamine ligand and two N atoms from two azide anions, resulting in a distorted square-pyramidal environment. A weak inter­molecular C—H⋯N hydrogen-bonding inter­action between one pyridine group of the ligand and an azide N atom of an adjacent complex unit gives a one-dimensional chain structure parallel to the c axis

    In the title compound, [Cu(NO3)2(C15H19N3O)], the CuII ion is coordinated by the N atoms of the tetradentate 3-[bis(2-pyridylmethyl)amino]propanol ligand and two O atoms from two monodentate nitrate anions, resulting in a distorted square-pyramidal environment. An intermolecular O—H...O hydrogen-bonding interaction between the free hydroxy group of the ligand and a nitrate O atom of an adjacent complex unit, gives a chain structure which extends across the (101) planes
