✦ Synopsis

I The etruc&al-Investigation of the complex AgN03(trana-cyclcdodecene)2 ha8 been undertaken ae part of a research on the structure of cyslooleflns performed ln'our laboratory In the last few yeara. Crystals of AgN03(tra~a-,C12H22)2 were prepared by &acting an aqueous solution of AgiNO3 iuith ti'solutlon. of C12H22 In ether. Pure trana-cyclododecene was obtained by means of chranatcgraphlc separation of a camneFcla1 mixture of qia and trane lscmere. ,: X-ray diffraction studies of single crystals of the caaplex sheed I$ to be orthoranblc; apace group Pbcn with unit cell dimension8 a = 5.46 2 ---O.OlAO, 2 = 14.50 2 0.031, 2 = 30.57 f 0.06;; Do = l;%g?cm -3pc -1.36 . g.cmm3), Z e 4.
