Abstract
The crystal structure of the new complex, CH3NH3NiCl3, has been determined. The compound crystallizes in the space group Cmcm with a=6.94, b=14.94, and c=5.95 Å. Each nickel ion has a distorted octahedral coordination with two chloride ions at 2.405 Å and four chloride ions at 2.351 Å. Adjacent octahedra along the c axis share faces to form infinite (NiCl3)nn— chains parallel to this axis. The electronic absorption spectrum has been measured over the range 6000–45 000 cm−1. The spectrum is characteristic of octahedral d8 complexes and yields a value of Dq=700 cm−1 for the nickel chloride complex.Keywords
