A new layered molybdenum cobalt phosphate, Na(2)[Co(H(2)O)(6)][(Mo(16)O(32))Co(16)(PO(4))(4) (HPO(4))(16)(H(2)PO(4))(4)(OH)(4)(C(10)H(8)N(2))(4)(C(5)H(4)N)(2)(H(2)O)(6)]·4H(2)O (1), has been hydrothermally synthesized and structurally characterized. 1 crystallizes in the monoclinic space group P2(1)/n with a = 15.6825(18) Å, b = 39.503(4) Å, c = 17.2763(17) Å, β = 93.791(2)°, V = 10679.4(18) Å(3), and Z = 2. A polyoxoanion of 1 exhibits an unusual organic-inorganic hybrid wheel-type cluster, in which two pyridine ligands link to the surface Co(II) atoms of a [H(24)(Mo(16)O(32))Co(16)(PO(4))(24)(OH)(4)(H(2)O)(6)] (namely, {Mo(16)Co(16)P(24)}) wheel via the Co-N bonds. Furthermore, each {Mo(16)Co(16)P(24)} wheel is connected to four adjacent wheels by four pairs of 4,4'-bipyridine linkers, forming a 2D layered network. The susceptibility measurement shows the existence of dominant antiferromagnetic interactions in 1.
一种新的层状钼钴磷酸盐，Na(2)[Co(H(2)O)(6)][(Mo(16)O(32))Co(16)(PO(4))(4) (HPO(4))(16)(H(2)PO(4))(4)(OH)(4)(C(10)H(8)N(2))(4)(C(5)H(4)N)(2)(H(2)O)(6)]·4H(2)O (1)，已经通过水热合成法合成并进行了结构表征。1 晶体属于单斜晶系 P2(1)/n 空间群，a = 15.6825(18) Å, b = 39.503(4) Å, c = 17.2763(17) Å, β = 93.791(2)°, V = 10679.4(18) Å(3), 和 Z = 2。1 的多氧阴离子表现出一种不寻常的有机-无机杂化轮型簇，其中两个吡啶配体通过 Co-N 键连接到[H(24)(Mo(16)O(32))Co(16)(PO(4))(24)(OH)(4)(H(2)O)(6)]（即，{Mo(16)Co(16)P(24)})轮的表面 Co(II)原子上。此外，每个{Mo(16)Co(16)P(24)}轮通过四对 4,4'-联吡啶连接体与四个相邻的轮连接，形成二维层状网络。磁化率测量表明 1 中存在主导的反铁磁相互作用。
