摘　　要：An inorganic-organic hybrid lanthanide selenidostannate [{Tb（en）3}2（μ-OH）2]Sn2Se6（1） was synthesized by the solvothermal method.1 crystallizes in the monoclinic system,space group P21/n with a=10.120（2）,b=11.781（3）,c=15.403（3）,β=99.534（5）°,V=1811.1（7）3,Mr=1423.62,Z=2,Dc=2.611 g/cm3,μ=11.281 mm-1,F（000）=1312,S=1.101,the final R= 0.0400 and wR=0.0853 for 3242 observed reflections with Ⅰ 〉2σ（Ⅰ）.1 consists of a [Sn2Se6]4-and a [{Tb（en）3}2（μ-OH）2]4＋ ions.The [Sn2Se6]4-anion is constructed by two SnSe4 tetrahedra sharing a common edge.The binuclear [{Tb（en）3}2（μ-OH）2]4＋ complex is composed of two [Tb（en）3]3＋ ions joined by two μ-OH bridging ligands.The Tb3＋ ion lies in an eight-coordinated bicapped trigonal prism.In 1,the [Sn2Se6]4-and [{Tb（en）3}2（μ-OH）2]4＋ moieties are connected into a 3-D network via N-H···Se and O-H···Se H-bonds.An inorganic-organic hybrid lanthanide selenidostannate [{Tb（en）3}2（μ-OH）2]Sn2Se6（1） was synthesized by the solvothermal method.1 crystallizes in the monoclinic system,space group P21/n with a=10.120（2）,b=11.781（3）,c=15.403（3）,β=99.534（5）°,V=1811.1（7）3,Mr=1423.62,Z=2,Dc=2.611 g/cm3,μ=11.281 mm-1,F（000）=1312,S=1.101,the final R= 0.0400 and wR=0.0853 for 3242 observed reflections with Ⅰ 〉2σ（Ⅰ）.1 consists of a [Sn2Se6]4-and a [{Tb（en）3}2（μ-OH）2]4＋ ions.The [Sn2Se6]4-anion is constructed by two SnSe4 tetrahedra sharing a common edge.The binuclear [{Tb（en）3}2（μ-OH）2]4＋ complex is composed of two [Tb（en）3]3＋ ions joined by two μ-OH bridging ligands.The Tb3＋ ion lies in an eight-coordinated bicapped trigonal prism.In 1,the [Sn2Se6]4-and [{Tb（en）3}2（μ-OH）2]4＋ moieties are connected into a 3-D network via N-H···Se and O-H···Se H-bonds.
