✦ Synopsis
ÁBr À is, to our knowledge, the ®rst reported example of a simple salt of cationic mono-Nprotonated 1,10-phenanthroline-5,6-dione. All of the atoms lie on a crystallographic mirror plane and the cation is therefore totally planar. As a consequence, the compound has a well de®ned layer structure in which NÐHÁ Á ÁBr, CÐHÁ Á ÁBr and CÐHÁ Á ÁO contacts within the layers interconnect the ionic species.

## Abstract We describe results relating to the effect of halide counterion in the ROMP of a permanently cationic __exo__‐7‐oxanorbornene derivative. Statistical copolymerizations of __exo__‐benzyl‐[2‐(3,5‐dioxo‐10‐oxa‐4‐aza‐tricyclo[5.2.1.0^2,6^]dec‐8‐en‐4‐yl)ethyl]dimethyl ammonium bromide/chlori
The title compound, C 28 H 26 N 4 O 7 , (I) crystallizes with two molecules in the asymmetric unit. It is a glycoluril derivative with five fused rings. A phenylethynyl-substituted benzene ring is fused to a seven-membered ring, which binds two of the N atoms from separate rings of the glycoluril sy
