Abstract:
The four title Cu(II) compounds are chloro[(2-furylmethyl)bis(2-pyridylmethyl)amine-N,N',N"]copper(II) perchlorate, [CuCl(C(17)H(17)N(3)O)]ClO(4), (I), chloro{2-[bis(2-pyridylmethyl)amino]ethanolato-N,N',N",O}copper(II) hemi[tetrachlorocopper(II)], [CuCl(C(14)H(17)N(3)O)][CuCl(4)](1/2), (II), chloro[(2-morpholinoethyl)bis(2-pyridylmethyl)amine-N,N',N",N"']copper(II) perchlorate, [CuCl(C(18)H(24)N(4)O)]ClO(4), (III), and chloro[(2-piperidinylethyl)bis(2-pyridylmethyl)amine-N,N',N",N"']copper(II) hexafluorophosphate, [CuCl(C(19)H(26)N(4))]PF(6), (IV). They have tripodal potentially tetradentate ligands. In (I), the O atom of the furan moiety weakly coordinates to the Cu atom at a distance of 2.750 (3) A.
