dc.titleInvestigation of the MSO(4) center dot xH(2)O (M = Zn, x=7; M = Cd, x=8/3)/methyl 2-pyridyl ketone oxime reaction system: A novel Cd(II) coordination polymer versus mononuclear and dinuclear Zn(II) complexesen
heal.abstractThe reactions of methyl 2-pyridyl ketone oxime, (py)C(Me)NOH, with MSO4 center dot xH(2)O (M = Zn, x = 7; M = Cd, x = 8/3), in the absence of an external base, have been investigated. The synthetic study has led to the two new complexes [Zn(SO(4)){(py)C(Me)NOH}(H(2)O)(3)] center dot H(2)O (1 center dot H(2)O) and [Zn(2)(SO(4))(2){(py)C(Me)NOH} (4)] center dot (py)C(Me)NOH [2 center dot (py)C(Me)NOH], and the coordination polymer [Cd(SO(4)){(py)C(Me)NOH} (H(2)O)](n) center dot [Cd(SO(4)){(py)C(Me)NOH}(H(2)O)(2)] n (3). In the three complexes the organic ligand chelates through its nitrogen atoms. The sulfate anion in 1 center dot H(2)O is monodentate; the complex molecule is the mer isomer considering the positions of the aqua ligands. The Zn(II) centers in 2 center dot (py)C(Me)NOH are bridged by two syn, anti eta(1): eta(1): mu(2) SO(4)(2-) ligands; each metal ion has the cis- cis-trans disposition of the coordinated sulfate oxygen, pyridyl nitrogen and oxime nitrogens, respectively. The molecular structure of 3 is unique consisting of two different linear and ladder - type chains. pi-pi stacking interactions and/or hydrogen bonds lead to the formation of interesting supramolecular architectures in the three complexes. The thermal decomposition of complex 3 has been studied. Characteristic vibrational (IR, Raman) bands are discussed in terms of the nature of bonding and the structures of the three complexes.
