| The co-planarity of the 4,4’-bipy rings can be roughly approximated where the torsion angle of C(6)-C(7)-C(8)-C(9) is 0.11 (0.55)o. The bond elongation between the C-atoms bridging the two aromatic rings of the 4,4’-bipy molecule {C(7)–C(8), 1.499(5) Å}, in comparison with those within the ring {(1.307(3)-1.388(3) Å}, should also be noted. The bond distances and angles of the 4,4’-bipy molecule fall within the range of values found in other similar 4,4’-bipy compounds [13].The metal-metal separation through the bridging 4,4’-bipy ligand is 11.192(11) Å, a value which lies within the range observed for 4,4’-bipy-bridged copper(II) complexes [13]. The Cu atoms are bridged by the 4,4’-bipy ligand with the nearest Cu…Cu separation forming an extended 1D [Cu(4,4’-bipy)(SO4)(H2O)3]n chains which runs parallel to the ab plane. Adjacent layers are rotated by 60o to produce virtual hexagonal cavities in projection along the crystallographic c-axis. The water molecules of crystallization occupy these hexagonal channels (Fig. 4). The hydrogen bonds involving the sulfate pendants and a free lattice water molecule lead to a 2D network, and cooperation with hydrogen bonds of another free lattice water molecule extend to 3D supramolecules as shown in Fig. 4 and Table 3. The packing diagram of (1) along the crystallographic c-axis produces hexagonal cavities accommodating the 4,4’-bipy rings and the H2O molecules of crystallization as shown in Fig. 5 [10]. |

| 4,4’-联吡啶环的共面大致可以近似其中C(6)-C(7)-C(8)-C(9) 的扭转角为0.11 (0.55)o。与那些在{(1.307(3)-1.388(3) Å}范围内的环相比，应该注意到4,4’-联吡啶分子中两个芳香环的桥碳原子间键延长{C(7)–C(8), 1.499(5) Å}。4,4’-联吡啶分子的键距和角度在其它类似4,4’-联吡啶化合物的数值范围内[13]。通过桥连的4,4’-联吡啶配体分开的金属-金属键是11.192(11) Å，这一值在研究过的4,4’-联吡啶桥连的二价铜离子配合物的范围内 [13]。被4,4’-联吡啶桥接的铜原子与最近的铜…铜分离形成一个与ab面平行延伸的一维[Cu(4,4’-bipy)(SO4)(H2O)3]n长链。在投影图中沿晶体的C轴相邻层通过60o的旋转产生虚拟的六边形空腔。晶体中的水分子占据这些六边形通道(见图4)。硫酸根基团和自由格水分子的氢键导致了一个二维网络,与另一个自由格水分子氢键链接延伸为三维超分子,如图4和表3所示。(1)的压缩图像沿着晶体的C轴生产六边形的空腔来容纳晶体中的4,4’-联吡啶环和水分子如图5[10]。 |

The co-planarity of the 4,4’-bipy rings can be roughly approximated where the torsion angle of C(6)-C(7)-C(8)-C(9) is 0.11 (0.55)o. 4,4’-联吡啶环的共平面可以粗略的渐进确定为C(6)-C(7)-C(8)-C(9)扭转角为0.11 (0.55)o的状态。 The bond elongation between the C-atoms bridging the two aromatic rings of the 4,4’-bipy molecule {C(7)–C(8), 1.499(5) Å}, in comparison with those within the ring {(1.307(3)-1.388(3) Å}, should also be noted. 桥接4,4’-联吡啶分子中两个芳香环的C原子间的键键长为{C(7)–C(8), 1.499(5) Å}，相比环内键长{(1.307(3)-1.388(3) Å}有所伸长，这也应引起注意。The bond distances and angles of the 4,4’-bipy molecule fall within the range of values found in other similar 4,4’-bipy compounds [13]. 4,4’-联吡啶分子的键长和键角与其它相似的 4,4’-联吡啶化合物中所发现的数值接近。The metal-metal separation through the bridging 4,4’-bipy ligand is 11.192(11) Å, a value which lies within the range observed for 4,4’-bipy-bridged copper(II) complexes [13]. 通过桥接的4,4’-联吡啶配位体的metal-metal separation 为11.192(11) Å ，此值与在4,4’-联吡啶桥接的铜（II）复合物中测得的相近。The Cu atoms are bridged by the 4,4’-bipy ligand with the nearest Cu…Cu separation forming an extended 1D [Cu(4,4’-bipy)(SO4)(H2O)3]n chains which runs parallel to the ab plane.铜原子通过4,4’-联吡啶配位体与最近的铜-铜separation相桥接，形成一个与ab平面平行的延伸的1维 [Cu(4,4’-bipy)(SO4)(H2O)3]n 链。Adjacent layers are rotated by 60o to produce virtual hexagonal cavities in projection along the crystallographic c-axis. 相邻的层旋转60°形成在晶体学c-轴方向投射的六角形空洞。The water molecules of crystallization occupy these hexagonal channels (Fig. 4).结晶中的水分子占据这些六角形空洞。 The hydrogen bonds involving the sulfate pendants and a free lattice water molecule lead to a 2D network, and cooperation with hydrogen bonds of another free lattice water molecule extend to 3D supramolecules as shown in Fig. 4 and Table 3. 硫酸修饰基和一个自由晶格水分子间的氢键导致2维网络形成，在与另一个自由晶格水分子的氢键的配合下延伸为图4和表3所示的3维超分子。The packing diagram of (1) along the crystallographic c-axis produces hexagonal cavities accommodating the 4,4’-bipy rings and the H2O molecules of crystallization as shown in Fig. 5 [10]. （1）的沿晶体学c-轴方向的压缩图像上可见到容纳4,4’-联吡啶环和结晶水分子的六角形空洞，如图5所示。 不懂你的专业，专业名词和概念请楼主自行校正 |
