Magnetic moment = 5.92 BM =√n(n+2) n = 5 = no. of unpaired electrons. It suggests

Q. $M n^{2 +}$ forms a complex with $B r^{-}$ ion. The magnetic moment of the complex is 5.92 BM. The probable formula and geometry of the complex, is

$[M n B r_{4}]^{2 -};$ tetrahedral

$[M n B r_{4}]^{2 -};$ square planar

$[M n B r_{6}]^{4 -};$ octahedral

$[M n B r_{5}]^{3 -};$ trigonal planar.

Magnetic moment $= 5.92 BM = n (n + 2)$
$n = 5 =$ no. of unpaired electrons.
