It is of orthorhomic crystal system and Pcad space group with a=16.260 (3), b=7. 739 (2). c=27. 530 (9) A, Mr=416. 97, Z=8. Dx=1. 595 g/cm3,μ=12. 876 cm-1, and F(000)=1736. The final R factor is 0. 061 for 2594 observed reflections with I>3σ(I). The Cu .atom is five coordinated to form a distorted square pyramid geometry in which N(11) of the pendant is at apical site.展开更多
