碳原子之间单键的最大长度是多少？当然，这个问题不能仅靠量子力学计算来回答--对真实分子进行可靠的物理测量至关重要。最近在四苯二氢环丁二烯1和2中发现了最长的明确确定的CC单键(1.72o)。
What is the maximum length of a single bond between carbon atoms? Certainly, this question cannot be answered by quantum mechanical calculations alone—reliably interpreted physical measurements on real molecules are crucial. The longest unequivocally determined C C single bonds (1.72 Å) have recently been found in tetraphenyldihydrocyclobutarenes 1 and 2.
