| Title of publication | Structural isomerism in (p-XC(6)H(4))SeCl(3) and (p-XC(6)H(4))SeBr(3) (X = F, Cl) compounds. Co-crystallisation of cis- and trans-dimeric forms of (p-ClC(6)H(4))SeCl(2)(μ-Cl)(2)(p-ClC(6)H(4))SeCl(2). A new structural modification for the "PhSeBr" reagent, Ph(2)Se(2)Br(2), containing an elongated Se-Se bond. |
