Abstract
Two coordination compounds[Zn(mtyaa) 2 (H 2 O) 4 ]·4H 2 O ( 1 ) and[Zn(bpe)(mtyaa) 2 (H 2 O) 2 ] n ( 2 ) (Hmtyaa=2-(5-methyl-1, 3, 4-thiadiazol-2-ylthio) acetic acid, bpe=1, 2-bis(4-pridyl)ethane) have been synthesized and they were structurally characterized by single-crystal X-ray diffraction, and then were characterized by elemental analysis, FTIR spectra, thermal analysis and powder X-ray diffraction. Compounds 1 and 2 crystallize in the triclinic and monoclinic, space group P 1 and C 2/ c , respectively. Face-to-face π-π interactions and hydrogen bonds between coordinated and free water molecules with carboxylate oxygen atoms connect single molecules in compound 1 into three dimensional network. Compound 2 is connected into three dimensional structure by hydrogen bonds between coordinated water molecules and carboxylate oxygen atoms or nitrogen atoms.CCDC:653462, 1 ;653467, 2 .
