Refinement on F2	H-atom parameters constrained
Least-squares matrix: full	Method = Modified Sheldrick w = 1/[σ2(F2) + ( 0.01P)2 + 0.86P], where P = [max(Fo2,0) + 2Fc2]/3
R[F2 > 2σ(F2)] = 0.025	(Δ/σ)max = 0.001
wR(F2) = 0.052	Δρmax = 0.37 e Å−3
S = 1.00	Δρmin = −0.52 e Å−3
2658 reflections	Extinction correction: Larson (1970), Equation 22
138 parameters	Extinction coefficient: 75 (8)
0 restraints	Absolute structure: Flack (1983), 1102 Friedel-pairs
Primary atom site location: structure-invariant direct methods	Flack parameter: 0.002 (10)
