Abstract:
The title compound crystallizes with two independent molecules in the unit cell. The two molecules are cis-trans isomers. Crystal data: orthorhombic, P2(1)2(1)2(1), a = 7.0417(6), b = 9.5341(9), c = 25.411(2) Angstrom, Z = 8. The crystal structure has been solved by automated Patterson methods and refined to R = 0.024 for 1843 observed reflections.
