## Abstract Models for the crystal structure of __cis__β1,4βpoly(2,3βdimethylβ1,3βbutadiene) are elucidated by the joint use of molecular mechanics and WAXS. The chain conformation can be predicted by using different sets of potential functions. A model of crystal structure calculated by molecular
The title compound (C 10 H 10 O 2 Br 2 ) crystallizes in the orthorhombic space group P2 1 2 1 2 1 with a = 5.0319(2)Γ , b = 13.5282(5)Γ , c = 15.6289(6)Γ , V = 1063.90(1)Γ 3 , Z = 4, D x = 2.01 g/cm 3 at T = 293(2)K. The structure was solved by direct methods and refined by full-matrix least-squares p
