Refinement on F2	H-atom parameters constrained
Least-squares matrix: full	w = 1/[σ2(Fo2) + (0.087P)2 + 39.1076P] where P = (Fo2 + 2Fc2)/3
R[F2 > 2σ(F2)] = 0.072	(Δ/σ)max = 0.001
wR(F2) = 0.205	Δρmax = 1.04 e Å−3
S = 1.21	Δρmin = −1.05 e Å−3
3251 reflections	Extinction correction: SHELXL97 (Sheldrick, 2008), Fc*=kFc[1+0.001xFc2λ3/sin(2θ)]-1/4
166 parameters	Extinction coefficient: 0.0064 (7)
