Preparation and properties of Cu(II) complexes with N,N’,N',N’’’-tetrakis(2-pyridylmethyl)-1,4,8,11-tetraazacyclotetradecane (tpmc) and pseudohalides(NCO- orNCSe-): Part II

Abstract

Two new Cu(II) complexes with N,N’,N",N’’’-tetrakis(2-pyridylmethyl) -1,4,8,11-tetraazacyclotetradecane (tpmc) and pseudohalides (NCO- or NCSe-) were isolated. Elemental analyses (C, H, N, Cu) corresponded to the formulas [Cu2(NCO)tpmc](ClO4)3. 2CH3CN and [Cu2(NCSe)2 tpmc] (ClO4)2. 2H2O. C2H5OH. The coordination mode of tpmc and these ambidentate pseudohalides, geometries spectral characteristics (VIS, IR) and other properties were compared with those of the previously described [Cu2(NCS)2tpmc] (ClO4)2. Antimicrobial activity towards selected bacteria and yeast was tested and found for the NCSe but not the NCO complex.

Dobijena su dva nova Cu(II) kompleksa sa N,N’,N’’,N’’’-tetrakis(2-piridilmetil)-1,4,8,11-tetraazacikotetradekanom (tpmc) i pseudohalogenidima (NCO– ili NCSe–). Elementalna analiza (C, H, N Cu) odgovarala je formulama: [Cu2(NCO)tpmc](ClO4)3. 2CH3CN i [Cu2(NCSe)2 tpmc](ClO4)2. 2H2O. C2H5OH. Način koordinacije tpmc-a i ovih ambidentatnih pseudohalogenida, geometrijski raspored, spektralne karakteristike (VIS, IR) i dr. su upoređene sa ranije opisanim [Cu2(NCS)2tpmc](ClO4)2. Antimikrobna aktivnost prema nekim bakterijama i gljivicama je testirana i nađena samo u slučaju NCSe kompleksa.
