Crystal structure of 1,4,8,11-tetra-methyl-1,4,8,11-tetra-azonia-cyclo-tetra-decane bis-[chlorido-chromate(VI)] dichloride from synchrotron X-ray data.


ABSTRACT: The crystal structure of title compound, (C14H36N4)[CrO3Cl]2Cl2, has been determined by synchrotron radiation X-ray crystallography at 220?K. The macrocyclic cation lies across a crystallographic inversion center and hence the asymmetric unit contains one half of the organic cation, one chloro-chromate anion and one chloride anion. Both the Cl- anion and chloro-chromate Cl atom are involved in hydrogen bonding. In the crystal, hydrogen bonds involving the 1,4,8,11-tetra-methyl-1,4,8,11-tetra-azonia-cyclo-tetra-decane (TMC) N-H groups and C-H groups as donor groups and three O atoms of the chloro-chromate and the chloride anion as acceptor groups link the components, giving rise to a three-dimensional network.
