Crystal structure determination: The crystal of title compound with dimensions of 0.08 mm × 0.08 mm × 0.06 mm was mounted on a Rigaku Saturn CCD area-detector diffractometer with a graphite-monochromated MoKα radiation (λ = 0.71073 Å) by using a phi and scan modes at 293(2) K in the range of 1.41º ≤ θ ≤ 25.02º. The crystal belongs to Monoclinic system with space group P21/c and crystal parameters of a = 13.913(3), b = 9.3426, c = 29.539(6) Å, α = 90.00, β = 101.99(3), γ = 90.00º, V = 3756.0(13)
