numbering scheme.
The bond angles in perchlorate ion at O-Cl(1)-O are found to be in the range of 106.3(2) – 113.08(15)

while
bond distances, Cl-O are found to be in the range 1.408(2) to 1.432(2) Å. The perchlorate ion indicates at lengthening
of the Cl – O bonds involving O(1), which were weakly coordinated to the Ni atom [Ni(1) – O(1) = 2.875(35) Å].
The Cl(1) – O(1) bond length was 1.408(2) Å, which was significantly shorter than the average of the other three Cl –
O bonds, 1.432(2) Å.
