I have solved a structure of an organometallic Pt complex in which the Pt atom is located on an inversion center. The asymetric unit is just half of the molecule so I have the Pt atom coordinated to two C and two P atom, only with one of each in the asymetric unit. After finishing the structure and doing the checkcif, I have the following alert:
PLAT232 Type_2 Hirshfeld Rigid-Bond Test (Metal-X) Pt1 P1
It is not the first time I have it, but in this occassion I was wondering if the fact of having two equivalent P atoms bonded to the Pt in the same direction might be the cause of increasing the adp of the Pt along the chemical bonds (since they are in the same direction, 180º). I am not sure if this has really sense at all, but I will very glad of reading your comments.
Many thanks in advance
