The crystal structure of gold trifluoride is not like that of any known RXg compound although it can be viewed as a distorted form of the other noble-metal trifluoride structures. ... 

Apart from the lanthanide and actinide trifluorides all of the transition-metal trifluoride structures known show the metal atom to be six-co-ordinated in fluorine. Indeed in only one other case, that of manganese tri-fluoride, is there an appreciable distortion from octahedral symmetry. The distortions may be correlated with the electronic configurations of the metal atoms. Table 4 shows that, in the first transition series tri-... 

In this paper, we provide evidence for the existence of Nip4, which can be kept indefinitely as a dry solid at -55 °C and below. In addition, three forms of NiFj have been prepared, their structures identified, these related to other first transition series trifluoride structures, and the oxidizing properties briefly described. NiPa and the three known forms of NiFs are seen to be thermodynamically unstable with respect to loss of Fr at 20 °C.
