The crystal structures of two unusual complexes [Cu(terpy)(N3)Cl]1 and [(Cu0.75Ni0.25(terpy)-(N3)2}2]·2H2O 2(terpy = 2,2′:6′,2″-terpyridine) have been determined at room temperature: 1. space group P21c. a= 10.586(5), b= 8.572(1), c= 16.396(3)A, β= 100.69(3)°, Z = 4, R=R′= 0.036, for 2818 reflections with I 3σ(I); 2, space group P21/c, a= 10.195(5), b= 9.996(3), c= 15.866(8)A, β= 91.10(5)°, Z= 4, R=R′= 0.055 for 3134 reflections with I 3σ(I). Complex 1 possesses the first known co-ordination… CONTINUE READING
