About Eudialyte GroupHide

Formula:

[N(1)N(2)N(3)N(4)N(5)]₃[M(1.1)M(1.2)]₃[M(2.1)M(2.2)M(2.3)]_3-6[M(3)M(4)]Z₃[Si₂₄O₇₂]Θ₄X(1)X(2)

N(1–5) = Na, H₃O⁺, K, Sr, REE, Ba, Mn, or Ca;
M(1) = Ca, Mn, REE, Na, Sr, or Fe;
M(2) = Fe, Mn, Na, Zr, Ta, Ti, K, Ba, or H₃O⁺;
M(3) and M(4) = Si, S, Nb,Ti, W, or Na;
Z = Zr, Ti, or Nb;
Θ = O, OH, or H₂O;
X(1) and X(2) = Cl, F, H₂O, OH, CO₃, SO₄, AlO₄, or MnO₄.

The silicate portion is an "abbreviation", usually expandable not only into two cyclic trisilicate and two cyclic nonasilicate groups, but additional Si-bearing groups

A complex (or extremely complex) group of trigonal cyclosilicates with both three-fold (Si₃O₉)^6- and nine-fold (Si₉O₂₇)^18- rings. In some members, two nine-fold rings are bridged by a single silicon atom to give a [(Si₉O₂₇)₂SiO]^34- group.

The general formula may not be "satisfactory": "(...) Moreover, the general formula of eudialytes was developed without regard for a number of large-cation sites that, in the Russian literature, are designated as A(6), A(7), and A(8). The first two sites are located between the M(2) site and the axial M(3) and M(4) sites. Most frequently, they are formed in low-iron minerals. While the third site is rare in occurrence (...)".

Symmetry may sometimes be lowered (at the point group level) due to complex ordering-related phenomena.

Chemical substitutions are, in part, governed by blocky isotypism.
