我们用扫描隧道显微镜报道了一种新的水聚集体结构。水分子在78K下在Cu（110）表面自组装成一维链状结构。该链呈现锯齿形结构，周期为7.2A，并增长到约1000A的长度。我们提出水六聚体沿链沿着交替排列。由于偶极相互作用而产生的链间排斥促进了一维链的生长。二维覆盖层仅在高覆盖率下形成。
We report a novel structure of water aggregate by means of scanning tunneling microscopy. Water molecules are self-assembled into one-dimensional chains on Cu(110) at 78 K. The chain exhibits a zigzag structure with a period of 7.2 A and grows to a length of approximately 1000 A. We propose that water hexamers are arranged alternately along the chain. Interchain repulsion due to dipole interaction facilitates the 1D chain growth. A two-dimensional overlayer develops only at high coverage.
