摘要

The asymmetric unit of the mononuclear mixed-ligand title complex, Cd(C13H18NO3)2(C12H8N2)#183;2H2O, contains two crystallographically independent mol#173;ecules that differ insignificantly in their geometrical parameters. In both, the CdII cation lies on a twofold rotation axis and is coordinated in a distorted octa#173;hedral fashion to two monodeprotonated residues of the l-leucine-derived ligand (S)-2-(2-hy#173;droxy#173;benzyl#173;amino)-4-methyl#173;penta#173;noic acid (L), as well as to a 1,10-phenanthroline ligand in a #954;2N,N#8242; mode. The former coordinate in an N,O-chelating mode, exhibiting a trans-N,N#8242; mutual disposition. The phenolic oxygen donor groups remain protonated and do not coordinate to the cation but take part in intra- and inter#173;molecular hydrogen bonds. In the crystal, O#8212;H#8943;O hydrogen bonding results in the formation of a three-dimensional network structure. The contribution to the electron density of two disordered water mol#173;ecules was removed with the SQUEEZE procedure in PLATON Spek (2015). Acta Cryst. C71, 9#8211;18. The studied crystal was refined as a two-component inversion twin. The title complex was also characterized by IR and 1H NMR spectroscopic methods.
