We systematically investigate the possibility that the s{sup 2} configuration of the two neutrons in the middle of the nucleus is a characteristic bond of {alpha}-clusters in light neutron-rich nuclei. The series of cluster states seen in {sup 10}Be(2{alpha}+2n) and {sup 14}C(3{alpha}+2n) is extended to the cases of heavier nuclei, {sup 18}O(4{alpha}+2n) and {sup 22}Ne(5{alpha}+2n), and we show the appearance of cluster structure with the s{sup 2} bond in the excited states by using a microscopic N{alpha}+2n model, in which the coupling with low-lying states is included.
