Refinement on F2	Primary atom site location: structure-invariant direct methods
Least-squares matrix: full	Secondary atom site location: difference Fourier map
R[F2 > 2σ(F2)] = 0.045	Hydrogen site location: mixed
wR(F2) = 0.115	H atoms treated by a mixture of independent and constrained refinement
S = 0.98	w = 1/[σ2(Fo2) + (0.0513P)2] where P = (Fo2 + 2Fc2)/3
4242 reflections	(Δ/σ)max < 0.001
178 parameters	Δρmax = 0.28 e Å−3
1 restraint	Δρmin = −0.70 e Å−3
