akis(3,5-dimethyl-1-pyrazolyl)cyclotriphosphazene, N(3)P(3)Ph(2)(dmpz)
(4) (2), forms mononuclear five-coordinate complexes N(3)P(3)Ph(2)(dmp
z)(4) . CuX(2) [X = Cl (3) and Br (4)] with copper(II) halides. The st
ructure of dichloromethane solvate of the chloro derivative, N(3)P(3)P
h(2)(dmpz)(4) . CuCl2, has been determined by single crystal X-ray dif
fraction. The metal exists in a distorted trigonal bipyramidal geometr
y and the ligand 2 acts as an N-3 capping tridentate ligand with two n
on-geminal pyrazolyl pyridine and one cyclotriphosphazene ring nitroge
n and two chloride ions complete the trigonal bipyramidal environment.
The spectroscopic (IR, UV-vis and EPR) characterization of the comple
xes is also reported.
