“…The formation of these hydroxides or halide-oxohydroxides is pHdependent and requires fine-tuned reaction parameters (e.g., alkali metal hydroxide or ammonium hydroxide solution, presence of crystallization additives like Cu(ClO 4 ) 2 ) [26,35,36].…”

“…Selected metrical data are given in Table 2. Compound 3 adopts a regular cage arrangement, which is typical of other members of the structurally characterized Sn 6 (O) 4 (OR) 4 family (R = H, 51 Me, 52 Pr i , 53 SiMe 3 49 ). The cage comprises two six-membered Sn 3 O 3 rings fused by Sn-O links between the two faces.…”

“…Abrahams et al (1996) reported simi- lar data for their synthetic material: a 7.9268, c 9.1025 Å, V 571.94 Å 3 , and D calc 4.904 g/cm 3 . Originally, Organ & Mandarino (1971) had adopted the triclinic cell of Donaldson (1961), and Howie & Moser (1968, 1973 had determined possible tetragonal space-groups P4/mnc or P4nc. The structure analysis of synthetic crystals by Abrahams et al (1996) revealed Sn 6 O 4 (OH) 4 clusters in a pseudo-body-centered arrangement, with intercluster hydrogen bonding between OH and O atoms.…”

The type material of romarchite and hydroromarchite from Boundary Falls, Winnipeg River, Ontario, Canada, was re-examined. The minerals form deposits on pewter bowls and are products of tin corrosion in a unique cold freshwater environment. Type romarchite is very fine-grained and replaces pseudotetragonal crystals of an unknown precursor. Revised X-ray powderdiffraction data are consistent with the accepted tetragonal symmetry and space group P4/nmm, and provide the refined unit-cell parameters a 3.8014(3), c 4.8559(6) Å. Type hydroromarchite forms euhedral single crystals. Revised X-ray powder-diffraction data are consistent with the accepted tetragonal symmetry and space group P42 1 c, and provide the refined unit-cell parameters a 7.9269(5), c 9.0970(9) Å. Additional Sn-bearing corrosion products are SnO 2 (cassiterite) and two unidentified phases. Residual aggregates of Pb, SbSn and Cu 6 Sn 5 (-bronze) are found in areas of deep localized corrosion. Reports of romarchite subsequent to the original description are numerous, but those of hydroromarchite are few and only quite recent. SOMMAIRENous avons ré-examiné les échantillons holotypes de la romarchite et de l'hydroromarchite provenant des chutes Boundary, sur la rivière Winnipeg, en Ontario, Canada. Ces minéraux se sont formés sur des bols enfouis en étain comme produits de la corrosion de l'étain dans un milieu unique d'eau fraîche froide. Le romarchite type a une granulométrie très fine et remplace des cristaux pseudotétragonaux d'un précurseur méconnu. Les données révisées obtenues en diffraction X, méthode des poudres, concordent avec la symétrie tétragonale acceptée et le groupe spatial P4/nmm, et mènent aux paramètres réticulaires affinés a 3.8014(3), c 4.8559(6) Å. L'hydroromarchite type forme des monocristaux idiomorphes. Les données révisées en diffraction X, méthode des poudres, concordent avec la symétrie tétragonale acceptée et le groupe spatial P42 1 c, et mènent aux paramètres réticulaires a 7.9269(5), c 9.0970(9) Å. Sont aussi présents comme produits de corrosion stannifères SnO 2 (cassitérite) et deux phases non identifiées. Des aggrégats résiduels de Pb, SbSn et Cu 6 Sn 5 (bronze-) ont été décelés dans des endroits où la corrosion était accentuée. Les indices de romarchite connus depuis sa découverte sont nombreux, mais ceux de la hydroromarchite sont peu nombreux et assez récents.(Traduit par la Rédaction) Mots-clés: romarchite, hydroromarchite, oxyde d'étain, étain, produit de corrosion, données en diffraction X, chute Boundary, Ontario, Canada. § E-mail address: bobr@rom.on.ca 650 THE CANADIAN MINERALOGIST tions of romarchite and hydroromarchite (gram and milligram quantities, respectively) on the two bowls registered under M28744 in the ROM mineral collections are designated holotypes. A considerable quantity of romarchite is also present on the bowl registered under M49593.
