The chromium co-ordination chemistry of three 1,3,5-triazacyclohexanes bearing hydroxyl-functionalised substituents on nitrogen has been explored. The complexes [CrL3(C3H6N3R3)] (L 4;= 4;CO, R 4;= 4;CH2CH2OH, CH2CH2CH2OH or o-hydroxybenzyl; L 4;= 4;Br, R 4;= 4;CH2CH2CH2OH) have been prepared. Characterisation of the carbonyl complexes by spectroscopic and structural methods indicated that the triazacyclohexanes co-ordinate to the chromium centre through the three nitrogen atoms only. Crystal structure determinations for 1,3,5-tri(o-hydroxybenzyl)-1,3,5-triazacyclohexane and [Cr(CO)3(C3H6N3R3)] (R 4;= 4;CH2CH2OH or CH2CH2CH2OH) have been made. |
