In contrast to the halide-bridged chain polymers (\n                    <jats:bold>I<\/jats:bold>\n                    ) and (\n                    <jats:bold>II<\/jats:bold>\n                    ), the adduct of\n                    <jats:bold>quinoz<\/jats:bold>\n                    with CdI\n                    <jats:sub>2<\/jats:sub>\n                    is the tetrahedral complex [CdI\n                    <jats:sub>2<\/jats:sub>\n                    (\n                    <jats:bold>quinoz<\/jats:bold>\n                    )\n                    <jats:sub>2<\/jats:sub>\n                    ], diiodidobis[quinazolin-4(3\n                    <jats:italic>H<\/jats:italic>\n                    )-one-\u03ba\n                    <jats:italic>N<\/jats:italic>\n                    <jats:sup>3<\/jats:sup>\n                    ]cadmium(II), [CdI\n                    <jats:sub>2<\/jats:sub>\n                    (C\n                    <jats:sub>16<\/jats:sub>\n                    H\n                    <jats:sub>12<\/jats:sub>\n                    N\n                    <jats:sub>4<\/jats:sub>\n                    O\n                    <jats:sub>2<\/jats:sub>\n                    )], (\n                    <jats:bold>III<\/jats:bold>\n                    ). The Cd\n                    <jats:sup>II<\/jats:sup>\n                    atom in this discrete complex is located on a twofold rotation axis. Disorder in (\n                    <jats:bold>III<\/jats:bold>\n                    ) is reflected in an alternative minority orientation of the molecules for which the iodine sites closely match the position of the majority orientation.
