We present a review of recent works on clustering phenomena in unstablenuclei studied by antisymmetrized molecular dynamics (AMD). The AMD studies inthese decades have uncovered novel types of clustering phenomena brought aboutby the excess neutrons. Among them, this review focuses on the molecule-likestructure of unstable nuclei. One of the earliest discussions on the clusteringin unstable nuclei was made for neutron-rich Be and B isotopes. AMDcalculations predicted that the ground state clustering is enhanced or reduceddepending on the number of excess neutrons. Today, the experiments areconfirming this prediction as the change of the proton radii. Behind thisenhancement and reduction of the clustering, there are underlying shell effectscalled molecular- and atomic-orbits. These orbits form covalent and ionicbonding of the clusters analogous to the atomic molecules. It was found thatthis "molecular-orbit picture" reasonably explains the low-lying spectra of Beisotopes. The molecular-orbit picture is extended to other systems havingparity asymmetric cluster cores and to the three cluster systems. O and Neisotopes are the candidates of the former, while the $3\alpha$ linear chains inC isotopes are the latter. For both subjects, many intensive studies are now inprogress. We also pay a special attention to the observables which are thefingerprint of the clustering. In particular, we focus on the monopole anddipole transitions which are recently regarded as good probe for theclustering. We discuss how they have and will reveal the exotic clustering.
