Abstract

Mr=510.6 triclinic $P \bar{1} \ $ (after structure solution and refinement) a=8.787 (2), b=9.907 (1), c=12.393 (3) Angstrom $ \alpha \ $=93.05 (6), $ \beta \ $=109.51 (6) $ \gamma \ $=97.93 $(6^0)$ U=1001.4 $Angstrom^3$ Z=2 Dc=1.67 $Mgm^-^3$ $ \mu \ $=14.13 $cm^-^1$ $ \lambda \ MoK_\alpha \ $=0.71069 Angstrom, F (000)=526 T=298K final R=0.047 and $R_w$=0.048 for 2479 reflections. The coordination polyhedron around Cu is an irregular square pyramid with the protonated saltrien (saltrien = $2-O-C_6H_8CH=N(CH_2)_2 NH(CH_2)_2NH(CH_2)_2NH2)$ acting as a tetradentate ligand coordinated to the metaL thruogh one 0 and three N atoms. The terminaL protonated nitrogen of the ligand is not coordinated and the apical position of the square pyramid is occupied by an oxygen of the perchlorate ligand.
