Synthesis and Crystal Structures of Chlororhenates(III) with the Divalent Cations Ethylenediammonium and Piperazinium: (EnH2)2(PipzH2) [Re3Cl12]2·6H2O, (EnH2) (PipzH2) [Re3Cl12]Cl· H2O, and (PipzH2) [Re3Cl11(H2O)] · 3H2OThe deep red salt (EnH2)2(PipzH2)[Re3CI12] · 6 H2O (1), (EnH2)(PipzH2)[Re3Cl12]CI · H2O (2), and (PipzH2)[Re3Cl11(H2O)] · 3H2O (3) crystallize upon evaporation from hydrochloride acid solutions of ReCl3 on addition of ethylenediammonium chloride (EnH2Cl2) and/or piperazinium chloride (PipzH2Cl2). The crystal structures have been determined from four-circle diffractometer data.1:monoclinic; a = 1889.63(11), b = 1615.82(8), c = 790.28(4)pm; β = 101.354(5)°; Z = 2; P21/n; R = 0.119, Rw = 0.070.2:triclinic; a = 1330.35(4), b = 1051.14(5), c = 1165.32(6)pm; α = 122.308(4), β = 102.412(3), γ = 92.226(4)°; Z = 2, P1; R = 0.092, Rw = 0.059.3:orthorhombic; a = 971.43(4), b = 1619.51(7), c = 1478.87(6)pm; Z = 4; Pbcm; R = 0.034, Rw = 0.032.
Notes:
Aus salzsauren Lösungen von ReCl3 und Ethylendiammoniumchlorid und/oder Piperaziniumchlorid kristallisieren beim Einengen der tiefroten Salze (EnH2)2(PipzH2) [Re3Cl12]2 m6H2O(1), (EnH2) (PipzH2)[Re3Cl12]CI · H2O (2), und (PipzH2) [re3Cl11(H2)] · 3H2O (3) aus. Ihre Kristallstrukturen wurden aus Vierkreisdiffraktometer-Daten bestimmt.1:monoklin; a = 1889,63(11), b = 1615,82(8), c = 790,28(4) pm; β = 101,354(5)°; Z = 2; P21/n; R = 0,119, Rw = 0,070.2:triklin; a = 1330,35(4), b = 1015,14(5), c = 1165,32(6) pm; α = 122,308(4), β = 102,412(3), γ = 92,226(4)°; Z = 2,P1; R = 0,092, Rw = 0,059.3:orthorhombisch; a = 971,43(4), b = 1619,51(7), c = 1478,87(6) pm; Z = 4; Pbcm; R = 0,034, Rw = 0,032.
