本文研究了Cu(PMBP)_2和HPMBP的单晶体结构,晶体学参数为:(1)HPMBP,C_(17)H_(14)0_2N_2,M=278.31,单斜晶系,空间群P2_1/a,a=11.406(5),b=9.087(1),c=13.467(3)(?),β=90.76(3)°,V=1395.7(?)~3,Z=4,D_c=1.324g cm~(-3),μ=0.95cm~(-1).(2)Cu(PMBP)_2,C_(34)H_(26)O_4N_4Cu,M=618.16,单斜晶系,空间群P_2_1/c,a=6.809(3),b=23.722(8),c=9.102(3)(?),β=108.94(4)°,V=1390.7(?)~3,Z=2,D_c=1.476g cm~(-3)tμ=8.67cm~(-1).结果表明,HPMBP具有烯醇式结构,其中两个给体氧原子处于有利于形成六元螯合环的几何位置;在配合物Cu(PMBP)_2中,Cu原子为对称中心,两个配体中的四个氧原子形成以Cu为中心的近似平面正方形的配位结构,Cu-O距离分别为1.906和1.896(?).
In this paper, the single crystal structures of Cu (PMBP) _2 and HPMBP were studied. The crystallographic parameters are as follows: (1) HPMBP, C17H14O2_2, M = 278.31, monoclinic, space group P2_1 / a, a = 3.406 (5), b = 9.087 (1), c = 13.467 (3) (?), Β = 90.76 (3) °, V = 1395.7 (?) ~ 3, Z = 4, D_c = 1.324g cm ~ (3), μ = 0.95cm -1. (2) Cu (PMBP) _2, C_ (34) H_ (26) O_4N_4Cu, M = 618.16, monoclinic system, space group P_2_1 / c, a = 6.809 (3), b = 23.722 (8), c = 9.102 (3) ?, β = 108.94 (4) °, V = 1390.7 (?) ~ 3, Z = 2, D_c = 1.476g cm ~ (-3) tμ = 8.67cm -1 .The results showed that HPMBP has enol structure, in which the donor oxygen atoms of two donors are in a geometric position conducive to the formation of six- PMBP) _2, the Cu atom is the center of symmetry and the four oxygen atoms in the two ligands form an approximately square planar coordination structure centered on Cu with Cu-O distances of 1.906 and 1.896, respectively.
