Description	A series of potassium isothiocyanato-(N-salicylidene-amino acidato)cuprates with the general formulas of K2[Cu2(sal-aa)2(mu-NCS)2].nH2O, where n = 0 or 4 and (sal-aa) stands for the dianion of N-salicylideneamino acid derived from glycine (I), dl-alpha-alanine (II), dl-valine (III), dl-phenylalanine (IV), and {K[Cu(sal-beta-ala)(mu-NCS)]}n for beta-alanine (V), respectively, was synthesized and fully characterized by elemental analysis, UV-Vis and IR spectroscopy, ESI-MS spectrometry, magnetic measurements, and X-ray structural analysis (II and IV). Moreover, the complexes were tested for their antibacterial activity against the G+ bacteria Staphylococcus aureus, G- bacteria Escherichia coli, filamentous fungi Microsporum gypseum, and yeast Candida albicans.
