Abstract: An equilateral-triangular shape of three

clusters surrounded by excess neutrons is suggested for
14
C
, based on the molecular-orbit model. It is found that the attractive interaction between an excess
neutron and an

particle stabilizes the
K


0

and
3

rotational bands, which demonstrates an
equilateral-triangular symmetry. This
K


3

band at 3 MeV below the
10
Be


threshold energy
corresponds to the experimentally observed band built on top of the second
3

state. A positive-parity
rotational band (
0

,
2

,
4

) arises similarly. These two bands suggest a molecular
3
-

structure
stabilized by the excess neutrons and can be viewed as a realization of the

crystallization in the dilute
nuclear medium
