-6 and 2 & -2 and 6 are the two pairs
0

-12= -1 X 12 (total no. of integers between them = 11)
     =  -2 X 6  (total no. of integers between them = 06)
     =  -3 X 4  (total no. of integers between them = 05)
     
=  -4 X 3  (total no. of integers between them = 05)
     
=  -6 X 2  (total no. of integers between them = 06)
     
= -12 X 1 (total no. of integers between them = 11)
Therefore, the possible pairs are (-1, 12) ans (-12, 1).
