Synthesis and Characterization of Two Chiral Cadmium Coordination Compounds Constructed from （1S,1′S）-1,1′-（4-amino-4H-1,2,4-triazole-3,5-diyl）diethanol

摘要

Two chiral cadmium coordination compounds,（S）-[Cd（deoatrz）2 Cl2]（1）and（S）[Cd（deoatrz）2 （NO3）2]（2）（deoatrz=（1S,1 S）-1,1-（4-amino-4H-1,2,4-triazole-3,5-diyl）diethanol）,are reported.Both 1 and 2 are mononuclear,crystallizing in tetragonal P41212 chiral space group with Z=2.For1,a=11.520（3）,b=11.520（3）,c=15.175（1）,V=2013.6（1）3,Mr=527.7,Dc =1.741 g/cm 3,μ=1.386mm-1,F（000）=1064,the final GOF=1.05,R=0.0147 and wR=0.0433 for1932 observed reflections with I〉2σ（I）.For 2,a=12.201（3）,b=12.201（3）,c=15.027（4）,V=2237.1（1）3,Mr=580.8,Dc=1.725 g/cm 3,μ=1.047mm-1,F（000）=1176,the final GOF=1.00,R=0.0201 and wR=0.0415 for 2408 observed reflections with I〉2σ（I）.Compounds 1 and 2 are connected into three-dimensional supramolecular networks through hydrogen bonding interactions.
