Mononuclear complexes and a coordination polymer of the 2-pyridylamino ((NHPy)-Py-2) functionalized P(V) ligand

Summary, in English

Three mononuclear metal complexes, [{PO2((NHPy)-Py-2)(2)}(2)M] [Py-2 - 2-pyridyl; M - Zn (1), Ni (2), Co (3)], have been synthesized by reacting metal nitrates with tetrakis(2-pyridylamino)phosphonium chloride, [P((NHPy)-Py-2)(4)]Cl, under solvothermal reaction conditions. The ligand, [P((NHPy)-Py-2)(4)]Cl, is hydrolyzed in the reaction medium. All of the complexes are isostructural and show an octahedral geometry around the metal ion. A coordination polymer, [{P((NHPy)-Py-2)(4)Cu2Cl4}ClO4](infinity) (4), was also obtained by treating [P((NHPy)-Py-2)(4)]Cl with copper perchlorate hexahydrate at ambient temperature. All of the complexes were characterized by standard analytical techniques. The solid-state structures of 1-4 were established by single crystal X-ray diffraction analysis. The optical properties of 1-4 have been investigated.
