Sažetak
Zinc is an essential metal and part of over 300 metalloenzymes [1]. Zinc coordination compounds involving amino acids are investigated due to pronounced antitumor, antibacterial and antifungal activities [1, 2]. However, crystallographic investigation of ternary coordination compounds involving zinc, amino acids and heterocyclic bases (2, 2'-bipyridine and its derivatives) is quite scarce. Only three crystal structures of such ternary coordination compounds were published [3]. As part of our ongoing investigation of ternary coordination compounds of essential metals, amino acids and heterocyclic bases [4], we report synthesis and crystal structure analysis of two novel ternary coordination compounds of zinc, L-serine (HSer) and 1, 10- phenanthroline (phen): [Zn(H2O)2(phen)2][ZnCl(Ser)(phen)]Cl2ꞏ3H2O (1·3H2O) and [Zn(H2O)2(phen)2][ZnCl(Ser)(phen)]2Cl2ꞏ7.5H2O (2·7.5H2O). Two types of complex entity are present in both coordination compounds, but in different stoichiometric ratios: cationic octahedral [Zn(H2O)2(phen)2]2+ and neutral square-pyramidal [ZnCl(Ser)(phen)] species. Both 1·3H2O and 2·7.5H2O contain infinite 1D channels of crystallization water molecules, occupying 10% and 17% of the unit cell volume, respectively (Figure 1).
