Why this differs from similar rows?
V0 taken from the linear V0-x relation of Hemley and Cohen; sibling row instead cites the Katsura and Ito relation (different original source and units, cm3/mol).

Evidence from the paper
compares well with V0 = 164.03 Å^3 given by Hemley and Cohen; linear relation V0(Å^3) = 162.48(7) + 6.2(7)x.
