摘要：

The dichloromanganese(IV) complexes with various bidentate and tetradentate Schiff base ligands, Mn-IV(L'),Cl-2 and Mn-IV(L)Cl-2 have been obtained by the reactions of chloromanganese(III) complexes, Mn-III(L')(2)Cl and Mn-III(L)Cl with hydrogen chloride or by the reactions of acetatomanganese(III) complexes, Mn-III(L')(2)OAc, with chlorine as deep green crystals, where L'H denotes bidentate Schiff base ligands N-R-salH (N-alkyl-salicylideneamine) and R can be n-C3H7, n-C6H13, n-C8H17, or n-C12H25, and LH, denotes tetradentate Schiff base ligands X-salenH, (N,N'-disubstituted-salicylideneethylenediamine) or X-salpnH(2) (N,N'-disubstituted salicylidenepropanediamine) and X can be H and 5-Br. X-ray structure analysis of the present dichloromanganese(IV) complexes has revealed that two chloride ions coordinate to the central manganese ion in a trans-form. (C) 2000 Elsevier Science Ltd.
