The crystal and molecular structure of 18-Crown-6 HgC12 and 18-Crown-6 Cdc12

Hg(18-Crown-6)C12 and Cd(18-Crown-6)C12 are isostructura1, space group Cl~ Z = 2. For the mercury compound, a = 10.444(2) A° , b = 11. 468(1) A° , c = 7.754(1) A° , a = 90.06(1)°, B = 82.20(1)°, Y = 90.07(1)°, Dobs = 1.87, Dca1c = 1.93, V = 920.05 13, R = 4.66%. For the cadmium compound, 000 a = 10.374(1) A, b = 11.419(2) A, c = 7.729(1) A, a = 89.95(1)°, B = 81.86(2)°, Y = 89.99(1)°, Dobs = 1.61, Dcalc = 1.64, V = 906.4613, R = 3.95%. The mercury and cadmium ions exhibit hexagonal bipyramidal coordination, with the metal ion located on a centre of symmetry in the plane of the oxygen atoms. The main differences between the two structures are an increase in the metal-oxygen distance and a reduction in the metalchloride distance when the central ion changes from Cd2+ to Hg2+. These differences may be explained in terms of the differences in hardness or softness of the metal ions and the donor atoms.

Fair Copyright for Canada: Lessons for Online Social Movements from the First Canadian Facebook Uprising

Despite their growing importance, the political effectiveness of social media remains understudied. Drawing on and updating resource mobilization theory and political process theory, this article considers how social media make “political engagement more probable,” and the determinants of success for online social movements. It does so by examining the mainstreaming of the Canadian “user rights” copyright movement, focusing on the Fair Copyright for Canada Facebook page, created in December 2007. This decentralized, grassroots, social media-focused action – the first successful campaign of its kind in Canada and one of the first in the world – changed the terms of the Canadian copyright debate and legitimized Canadian user rights. As this case demonstrates, social media have changed the type and amount of resources needed to create and sustain social movements, creating openings for new groups and interests. Their success, however, remains dependent on the political context within which they operate.
