ISOLATION, X-RAY STRUCTURE, AND IMMOBILIZATION ON SILICA SURFACES OF 5-AMINOMETHYL-5,12-DIMETHYL-1,4,8,11-TETRAAZACYCLOTETRADECA-11-ENENICKEL(II) DIPERCHLORATE MONOHYDRATE

Abstract

The violet “arm on” title complex (1) has been isolated. It crystallizes in the orthorhombic space group P2₁2₁2₁ with a = 10.184 (2), b = 12.719 (2), c = 17.096 (2) Å, V = 2214.4 ų, Z = 4 and was refined to R(R _w ) = 0.060 (0.066) for 1693 reflections. The complex was attached to γ-carboxypropylsilica. The “blue-to-yellow” conversion for bound complex is not completely reversible due to hydrogen bonding of complex species with the silica surface.
