摘要
Hydrothermal reaction of MgCl 2 and ethyl tetrazolate-5-carboxylate at 160 ℃ unexpectedly yielded compound {(H 3 O)[Mg(H 2 O) 6 ]Cl 3 } (1).The result of X-ray diffraction analysis indicates that 1 crystallizes in the monoclinic system,space group C2/c with a=9.2896(3),b=9.5570(4),c=13.3169(5),β=90.1221(12)°,V=1182.28(8)3,Z=4,M r=257.78,D c=1.448 g/cm 3,μ=0.824 mm-1,F(000)=536,R=0.0265 and wR=0.0706.1 is composed of one hexa-aqua-magnesium(II) ion,one hydroxonium ion,and three chlorine anions.These three com-ponents weave a perfect three-dimensional (3D) (4,4,6,12)-connected hydrogen bonding network within 1.
