A　binuclear　cuprous　complex　[Cu(mu-I)(NP)](2)center　dot　CH2Cl2　(1,　NP　=　1-(2-(diphenylphosphino)　phenyl)-3,5-dimethylpyrazole)　was　synthesized　and　characterized　by　elemental　analysis,　NMR,　UV-Vis　and　X-ray　single-crystal　structure　analysis.　It　crystallizes　in　triclinic　space　group　P　(1)　over　bar　with　a　=　9.2838(6),　b　=　12.2672(7),　c　=　12.4033(7)　angstrom,　alpha　=　114.941(6),　beta　=　108.707(5),　gamma　=　91.717(5)degrees,　V　=　1190.51(12)　angstrom(3),　Z　=　1,　M-r　=　1178.58,　D-c　=　1.644　g/cm(3),　F(000)　=　582,　mu　=　13.232　mm(-1),　GOOF　=　1.016,　the　final　R　=　0.0384　and　wR　=　0.1015　for　4145　observed　reflections　with　I　＞　2　sigma(I).　The　Cu　atoms　in　the　complex　are　four-coordinated　and　adopt　a　distorted　tetrahedral　coordination　geometry.　In　the　solid　state,　the　complex　exhibits　blue　photoluminescence　with　a　peak　maximum　of　468　nm,　a　decay　time　of　9　mu　s,　and　a　photoluminescence　quantum　yield　of　16.8%　at　room　temperature,　respectively.　The　studies　of　varied　temperature　emission　spectra　and　decay　behaviours　of　the　complex　indicate　that　the　complex　displays　thermally　activated　delayed　fluorescence　(TADF)　at　room　temperature.　The　results　of　experimental　and　DFT　calculations　suggest　that　the　excited　states　in　the　solid　state　are　of　(M+X+L)　LCT　character.
