Abstract

New coordination compounds [{MnIII(L)·(CH3OH)2}2{FeII(CN)5(NO)}]·2CH3OH was synthesized and structurally characterized by X-ray single-crystal diffraction. The structural analyse shows that complex consist of the discrete linear trinuclear [{MnIII(L)·(CH3OH)2}2{FeII(CN)5(NO)}] unit, where the nitroprusside Fe(II) anion coordinates to the axial sites of the two [MnIII(L)]+ (H2L = N1,N4-bis(salicylidene)-S-methylisothiosemicarbazide) entities through its two trans-cyanido nitrogen atoms. Elemental analysis and IR confirms the purity of the final product. Keywords: N1,N4-bis(salicylidene)-S-methylisothiosemicarbazide, managanese(III) complex, nitroprusside, crystal structure, IR.
