| 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]. |

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’-聯(lián)吡啶環(huán)的共平面可以粗略的漸進(jìn)確定為C(6)-C(7)-C(8)-C(9)扭轉(zhuǎn)角為0.11 (0.55)o的狀態(tài)。 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. 橋接4,4’-聯(lián)吡啶分子中兩個(gè)芳香環(huán)的C原子間的鍵鍵長為{C(7)–C(8), 1.499(5) Å}，相比環(huán)內(nèi)鍵長{(1.307(3)-1.388(3) Å}有所伸長，這也應(yīng)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’-聯(lián)吡啶分子的鍵長和鍵角與其它相似的 4,4’-聯(lián)吡啶化合物中所發(fā)現(xiàn)的數(shù)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]. 通過橋接的4,4’-聯(lián)吡啶配位體的metal-metal separation 為11.192(11) Å ，此值與在4,4’-聯(lián)吡啶橋接的銅（II）復(fù)合物中測得的相近。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.銅原子通過4,4’-聯(lián)吡啶配位體與最近的銅-銅separation相橋接，形成一個(gè)與ab平面平行的延伸的1維 [Cu(4,4’-bipy)(SO4)(H2O)3]n 鏈。Adjacent layers are rotated by 60o to produce virtual hexagonal cavities in projection along the crystallographic c-axis. 相鄰的層旋轉(zhuǎn)60°形成在晶體學(xué)c-軸方向投射的六角形空洞。The water molecules of crystallization occupy these hexagonal channels (Fig. 4).結(jié)晶中的水分子占據(jù)這些六角形空洞。 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. 硫酸修飾基和一個(gè)自由晶格水分子間的氫鍵導(dǎo)致2維網(wǎng)絡(luò)形成，在與另一個(gè)自由晶格水分子的氫鍵的配合下延伸為圖4和表3所示的3維超分子。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）的沿晶體學(xué)c-軸方向的壓縮圖像上可見到容納4,4’-聯(lián)吡啶環(huán)和結(jié)晶水分子的六角形空洞，如圖5所示。 不懂你的專業(yè)，專業(yè)名詞和概念請樓主自行校正 |
