Structural and magnetic studies of electrochemically crystallized halides of 1,4,5,8-tetraselenonaphthalene (TSeN)

Experimental conditions are described for the growth of single crystals by anodic electrocrystallization of the isomorphous chloride and bromide of 1,4,5,8-tetraselenonaphthalene (TSeN). The chloride of TSeN, [C 10 H 4 Se 4 ]Cl, is an orthorhombic crystal of space group Cmca with a=19.110 (4) A, b=8.574 (2) A, c=13.437 (3) A, V=2201.6 A 3 , and Z=8
