摘要
The title compounds（PySe）2 1（HPySe=2-pyridineselenol N-oxide,（PySe）2= bis（2-pyridine-N-oxide） diselenide） and Bi2（PySe）6 2 were prepared by the reaction of 2-bromine-N-oxide with NaHSe and Bi（NO3）3·5H2O with HPySe,and the crystal structure of 2 was studied.Compound 2 crystallizes in the monoclinic space group P21/n with a=9.840（2）,b=10.204（2）,c=18.395（2）,β=102.926（2）°,V=1800.0（5）3,Dc=2.2687 g/cm3,Z=2,the final R=0.0319 and wR=0.0646.The Bi atoms are coordinated by four selenium and four oxygen atoms from four PySe ligands to form a slightly distorted four-column geometry.
