摘　　要：The title compound, N-（1′-H-pyrrol-2′-ylcarbonyl）-5-amino-1,10-phenanthroline, was synthesized by the reaction of a-pyrrolyl carbonyl chloride and 5-amino-1,10-phenanthroline in pyridine. Determined by X-ray structure analysis, it crystallizes in triclinic system, space group P1 with the following crystallographic data： C20H21N5O3, Mr = 379.42, a = 7.8559（4）, b = 9.1681（6）, c = 14.6818（9） A, α= 73.254（10）,β= 88.938（15）, γ= 68.080（10）°, V= 934.66（10） A3, Z = 2, F（000） = 400, Dc = 1.348 g/cm^3 and p = 0.094 mm-1. The final R = 0.0680 and wR = 0.1419 for 2142 observed reflections with I 〉 2σ（/）, and R = 0.1084 and wR = 0.1643 for all reflections. Two aromatic ring planes （pyrrole and phenanthroline rings） are connected by the amide plane. Two different types of intermolecular hydrogen bonds, O-H…N and N-H…O, exist in the crystal. The title complex molecules are connected through hydrogen bonds and weak π-π stacking interactions to generate a 3-D supramolecule.The title compound, N-（1′-H-pyrrol-2′-ylcarbonyl）-5-amino-1,10-phenanthroline, was synthesized by the reaction of a-pyrrolyl carbonyl chloride and 5-amino-1,10-phenanthroline in pyridine.
