Utahite was first described in 1997 based mainly on powder X-ray diffraction data and electron microprobe data. No crystal structure was reported. The re-examination of utahite using single-crystal X-ray diffraction and electron microprobe analysis has shown that utahite contains essential Mg, along with Cu, Zn, Te, O and H. The missing MgO was originally attributed to additional H₂O. The redefinition of utahite to MgCu²⁺₄Zn₂Te⁶⁺₃O₁₄(OH)₄·6H₂O from Cu²⁺₅Zn₃(Te⁶⁺O₄)₄(OH)₈·7H₂O has been accepted by the IMA–CNMNC, Proposal 20-C. Utahite is triclinic, crystallising in P\(\overline{1}\) with the unit-cell parameters a = 5.6831(4) Å, b = 8.7793(6) Å, c = 9.9818(9) Å, α = 95.415(7)°, β = 104.129(7)°, γ = 90.098(6)° and V = 480.65(7) ų, in good agreement with the original study. Utahite features a new framework arrangement of Cuφ₆ octahedra, Znφ₄ tetrahedra and Teφ₆ octahedra (where φ = O or OH), with Mg(H₂O)₆ octahedra occupying the channel space. Two-thirds of the Te sites form Te^6 + ₂O₁₀ dimers and one third form [Te⁶⁺O₄(OH)₂]⁴⁻ octahedra, spatially separated from other Te⁶⁺ sites. Although unique, the structural framework of utahite is similar to that of leisingite, with both minerals having layers composed of Cuφ₆ and Teφ₆ octahedra with Mg(H₂O)₆ octahedra in the interlayer space; however leisingite does not contain Zn. New Raman spectroscopic data is also reported for utahite.

首次以粉末X射线衍射数据和电子微探针数据为基础，于1997年首次对犹他石进行了描述。没有晶体结构的报道。使用单晶X射线衍射和电子探针分析对铀矿的重新检查表明，铀矿包含必需的Mg以及Cu，Zn，Te，O和H.丢失的MgO最初归因于额外的H ₂ O.从U ₂到Cu ²⁺ ₅ Zn ₃（Te ⁶⁺ O ₄）₄（OH）₈重新定义Utahite为MgCu ²⁺ ₄ Zn ₂ Te ⁶⁺ ₃ O ₁₄（OH）₄ ·6H ₂ O·7H ₂ O具有被IMA-CNMNC接受，提议20-C。犹他州是三斜晶，在P \（\ overline {1} \）中结晶，晶胞参数a  = 5.6831（4）Å，b  = 8.7793（6）Å，c  = 9.9818（9）Å，α  = 95.415（ 7）°，β  = 104.129（7）°，γ  = 90.098（6）°和V  = 480.65（7）³，在与原来的研究吻合。Utahite设有Cuφ的一个新的框架结构₆八面体，Znφ ₄四面体和Teφ ₆八面体（其中，φ= O或OH），用Mg（H ₂ O）₆八面体占据了通道空间。Te位置的三分之二形成Te ^{6 +}  ₂ O ₁₀二聚体，三分之一形成[Te ⁶⁺ O ₄（OH）₂ ] ^4-八面体，与其他Te ⁶⁺位置在空间上分开。虽然独特，utahite的结构框架是类似于leisingite的，与具有Cuφ构成的层既矿物质₆和Teφ ₆用Mg八面体（H ₂ O）₆八面体在层间空间中; 然而，绿铅矿不含锌。还报道了关于utahite的新的拉曼光谱数据。
