The structure consists of an InCl fragment bonded symmetrically to the four N atoms of the macrocyclic ligand tmtaa (chloro3,5,14,16-tetramethyl-2,6,13,17-tetraaza-tricyclo[16.4.0.0(7,12)]docosa-1(18),2,5,7(12),8,10,13,16,-19,21-decaenediido-N,N,N'',N'''}indium). This is the first structural characterization of an In entity coordinated to this ligand and reveals an unusual five-coordinate square-pyramidal geometry around the In atom. The metal is displaced 0.738 (3) angstrom above the N4 coordination plane. The average In-N bond distance is 2.165 (5) angstrom and the In-Cl distance is 2.380 angstrom.
