New cationic Cu(II) and Co(II) complexes with  N,N',N'',N'''-tetrakis(2-pyridylmethyl)-1,4,8,11-tetraazacyclotetradecane  (tpmc) and the anion of 2-amino-3-phenyl-propanoic acid (S-phenylalanine)  were prepared. The complexes were analyzed and characterized by elemental  analysis, conductometric, polarimetric, magnetic and cyclic voltammetric  measurements, as well as by spectroscopic data (UV/Vis, IR). Both complexes  are binuclear with the general formula [M2(S-Phe)tpmc](ClO4)3∙nH2O; S-PheH =  S-phenylalanine, M(II) = Cu, n = 7; Co, n = 0. Based on previously reported  data for some familiar complexes and the present results, pentacoordinated  geometry was proposed. Both of the central metal ions are coordinated with  two pyridyl and two cyclam nitrogens and bridged with -N-(CH2)3-N- portions  of the cyclam ring and oxygen atoms of the S-phenylalaninate ion.  Antimicrobial screening of the complexes, solvent, starting salts and  ligands alone was performed against fungi, mould and some bacteria. In  certain cases, enhanced activity of Co(II) complex towards bacteria compared  with the relevant free ligands and starting salts was detected.
