在水热条件下对钴- OH - BDC - bpp体系的探索，导致了一个新的框架[Co(OH - BDC)(bpp)0.5(H2O)]n （OH - BDC = 5‐羟基间苯二甲酸，bpp = 1,3‐双（4‐吡啶基）丙烷）的分离。单晶X射线分析表明，它在单斜空间群P21/n中结晶。= 10.235 (8), b = 17.882 (14), c = 14.291(11),β= 92.107(9)°。钴离子通过氢键相互作用通过OH - BDC和单配位bpp配体连接成一个延伸的螺旋链。此外，这些螺旋链通过桥接bpp结合在一起形成二维层，相邻链具有相反的手性。（©2008 WILEY‐VCH Verlag GmbH & Co.

An exploration of the cobalt‐OH‐BDC‐bpp system under hydrothermal conditions, has led to the isolation of a novel framework [Co(OH‐BDC)(bpp)0.5(H2O)]n (OH‐BDC = 5‐hydroxyisophthalic acid, bpp = 1,3‐bi(4‐pyridyl)propane). Single‐crystal X‐ray analysis reveals that it crystallizes in the monoclinic space group P21/n. a = 10.235(8) Å, b =17.882(14) Å, c = 14.291(11) Å, β = 92.107(9)°.The cobalt ions are linked into an extended helical chain via OH‐BDC and mono‐coordinated bpp ligands through hydrogen‐bonding interactions. Further these helical chains are united together through the bridging bpp to form a 2D layer and the adjacent chains possess the opposite chirality. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
