Abstract
The tridentate macrocyclic ligands 1,4,7-triazacyclononane, its thia analogue 1,4,7-trithiacyclononane, 1-oxa-4,7-diazacyclononane, and N,N′,N″-trimethyl-1 ,4,7-triazacyclononane react with Re(CO)5Br in dimethylformamide to yield colorless, air-stable [LRe(CO)3]Br complexes (L = tridentate macrocycle). With Mn(CO)5Br only the cyclic amines react to afford yellow-orange [LMn(CO)3]Br complexes whereas 1,4,7-trithiacyclononane does not give stable complexes of manganese. The crystal structures of [([9]aneN3)Re(CO)3](NCS) and [([9]aneS3)Re(CO)3]Br · 1/2 H2O have been determined. The former crystallizes in the orthorhombic space group P bca (a = 12/763(4), b = 12.662(5), c = 17.472(9) Å; Z = 8); whereas the latter crystallizes in the monoclinic space group P21/c (a = 9.444(1). b = 11.797(2), c = 28.095(3) Å. β = 90,86(1); Z = 8).Keywords
