摘　　要：One novel 3D 3d-4f coordination polymer, [LaZn（glc）（ox）2（H20）2]n （1, glc = glycinate, ox = oxalate）, was obtained by the in situ synthesis of glycinate from the reaction of tetrazole-l-acetic acid, sodium oxalate, zinc nitrate and lanthanide oxide in the presence of a trace quantity of nitric acid under hydrothermal conditions. Compound 1 is of monoclinic, space group P21/n with a = 0.99601（9）, b = 1.14592（10）, c = 1.19107（10） nm and β = 108.7150（10）°. 1 exhibits an unusual 3D heterometallic coordination framework constructed by heterometallic dinuclear LaZn subunits and mixed ox and glc linkers with a uninodal 6-connected vine {33.43.58.6} net.One novel 3D 3d-4f coordination polymer, [LaZn（glc）（ox）2（H20）2]n （1, glc = glycinate, ox = oxalate）, was obtained by the in situ synthesis of glycinate from the reaction of tetrazole-l-acetic acid, sodium oxalate, zinc nitrate and lanthanide oxide in the presence of a trace quantity of nitric acid under hydrothermal conditions.
