Il y a [...] deux possibilités : 1° Holoédrie [...] : Molécule et réseau ont les mêmes éléments de symétrie - l'ensemble : le cristal possède tous les éléments de symétrie; 2° Mériédrie : Le réseau n'a pas tous les éléments de symétrie de la molécule, mais seulement une partie [...] La loi de symétrie n'est vérifiée que pour une partie des éléments.

Record number: 2, Textual support number: 1 CONT
En un cristal hemiédrico los átomos se encuentran ordenados de tal forma que desaparece uno de los elementos de simetría. La blenda, por ejemplo, cristaliza en forma de cubos pero su simetría es la de un tetraedro. Una troncadura de uno de sus vértices no se repite en los otros siete, sino solamente en tres. En el caso de que esas troncaduras se extiendan en la masa del cristal, pueden llegar a formarse dos tetraedros conjugados cuyas caras no tienen las mismas propiedades. 1, record 2, Spanish, - hemi%C3%A9drico

Une macle est un cristal complexe, semblant formé de deux cristaux jumeaux ou de deux demi-cristaux juxtaposés suivant une loi définie et non d'une façon accidentelle. Le plus souvent, ces deux cristaux élémentaires sont accolés suivant une face plane (face d'association), ayant la même notation pour les deux individus maclés, et l'un deux se trouve placé par rapport à l'autre dans la situation qu'on obtiendrait en faisant tourner celui-ci d'un angle déterminé autour d'un axe, dit «axe d'hémitropie». 3, record 3, French, - axe%20d%27h%C3%A9mitropie
