Answer to Question #196757 in Inorganic Chemistry for Fana

Question

Determine the multiplication of symmetry operations and elements below (to commute or do not commute)

a) [MnCl2Br2(H2O)2]2- octahedral molecule

i. C2 (at X axis) x C2 (at Br1-Mn-Cl2) = h (at Br1, Br2, Mn, Cl2, Cl2) x v (at C2 axis)

ii. i (at Mn) x C4 (at X axis) = C1 (at X) x C2 (at Br1-Mn-Cl2)

iii. E (at C2) x C2 (at Br2-Mn-Cl1) = E (Br2-Mn-Cl1) x i (at Mn)

b) Pyramid molecule – [Pd(OH)Br2H2]2-

i. C2 (at Pd-OH) x S4 (at Pd-OH) = σv (at the arrow given) x σh (at

planar of pyramid)

ii. σv (at H-Pd-Br) x σv (at H-Pd-Br) = S2 (at Pd-OH) x C4

(at Pd-OH)

Answer 1

a) C2 (at X axis) x C2 (at Br1-Mn-Cl2) = h (at Br1, Br2, Mn, Cl2, Cl2) x v (at C2 axis)

b) C2 (at Pd-OH) x S4 (at Pd-OH) = σv (at the arrow given) x σh
