摘要：

The solid-state structures of five new tri-arylphosphine silver cyclic amide complexes having a systematic variation in the ring structures have been resolved. Normal Ag—N bonding and variable, weaker Ag—O bonding interactions, which can be attributed to the ring modifications, form the basis of the bonding patterns. Reported here are the solid-state structures of silver complexes of tri-arylphosphine derivatives of silver 1(2 H )-phthalazinone, silver phthalimide, silver 1,2,3-benzotriazin-4(3H)-one, silver 2 H -1,3-benzoxazine-2,4(3 H )-dione and silver 2,3-dihydro-1,4-phthalazine- dione. The unit cell parameters are: P-1, a =11.179(2), b =15.508(3), c = 22.636(5), α=104.30(3)°, β=95.39(3)°, γ=94.62(3)°; C2/c, a =17.3600(8), b =15.4930(8), c =15.0760(7), β=113.911(2)°; P-1, a =11.0656(2), b = 11.9447(2), c =17.4764(3), α=79.5254(9)°, β=80.2877(9)°, γ=68.9136(7)°; P-1, a =10.5743(4), b =11.8439(4), c =19.0110(8), α=102.4280(13)°, β=104.0330(12)°, γ=100.2520(18)°, P-1, a =13.6908(3), b =16.2230(4), c =18.3678(7), α=86.8920(10)°, β=69.5290(10)°, γ=70.7840(10)°, respectively. Four of the complexes include ligand chelation by Ag—O bonding to the adjacent carbonyl in addition to the main Ag—N connection.
