Abstract

The tridentate schiff base ligand, salicyliden amino-o-hydroxy benzene, has derived from salicylaldehyde and o-amino phenol. This ligand reacts with a series of Mo (VI), Mo (V), Mo (IV), and Mo (III) oxidated states and forms a new complexes; [Mo O$_2(H_2O)\;(C_{13}H_9O_2N)]$, [MoO Cl$(H_2O)\;(C_{13}H_9O_2N)]$, [Mo(SCN)$_2(H_2O)\;(C_{13}H_9O2_N)]$ 및 $[Mo(H_2O)_2\;(C_{13}H_9O_2N)]_2O$. The Mo (VI), Mo(V) and Mo(Ⅳ) ions in these complexes are octahedron, hexa coordinate, and the mole ratio of these ions to the ligand are 1 : 1, but Mo (III) Complex is a Mo-O-Mo oxygen bridge bond and polynuclear, and the mole ratio of Mo (III) to the ligand 1 : 1 above facts are identified from the data of Infrared spectra, visible spectra, and elemental analysis.

세자리 schiff base리간드로서 salicylidene amino-o-hydroxy benzene 은 salicylaldehyde와 o-amino phenol로서 합성하였으며 이 세자리 schiff base 리간드와 Mo(VI), Mo(V), Mo(IV) 및 Mo(III) 의 과산화상태의 몰리브덴 착물들의 반응으로 새로운 착물[Mo O$_2(H_2O)\;(C_{13}H_9O_2N)]$, [MoO Cl(H$_2O)(C_13H_9O_2N)]$, $[Mo(SCN)_2(H_2O)(C_{13}H_9O2_N)]$ 및 $[Mo(H_2O)_2 (C_{13}H_9O_2N)]_2O$들을 얻었다. 이들 착물에서 Mo(VI), Mo(V) 및 Mo(IV)착물들은 리간드와 몰리브덴의 mole비가 1:1인 착물로서 몰리브덴 이온은 6배위 팔면체로서 주어지나 Mo(III) 착물은 Mo-O-Mo의 산소 bridge bond를 갖는 poly nuclear 착물로서 mole비 1:1인 착물로 주어짐을 원소분석치와 자외선흡광도 및 적외선 spectra의 고찰로서 알아보았다.
