摘要：
In the structure of aquachloro[7,10,13-trioxa-3,17,23-triazabicyclo[17.3.1] tricosa-1 (23),2,17,19,21-pentaene-N,N′,N″]copper(II) hexafluorophosphate acetonitrile solvate, the CuII ion is pentacoordinate with square-pyramidal coordination geometry, with a relatively long axial bond to water [2.244 (5) angstroms] and with the shortest Cu-N bond being to the pyridine N atom. The water molecule is also hydrogen bonded to two O atoms of the ligand. The complex is folded about the N-Cu-N axis, the polyether chain being nearly planar and making an angle of about 135° with the pyridine ring.
