采用水热方法合成了1个新的Ni（Ⅱ）配合物｛[Ni3（dcp）2（phen）2（H2 O）6]·4 H2 O｝（H3 dcp＝吡唑-3，5-二羧酸）。对该配合物进行了单晶 X 射线衍射结构表征及UV-Vis-NIR吸收光谱，IR光谱和表面光电压光谱（SPS）性质测定。结构分析表明，该配合物为三核Ni（Ⅱ）配合物，其中2个Ni（Ⅱ）离子[Ni2（Ⅱ）、Ni2A（Ⅱ）]是晶体学等效的，另外1个Ni1（Ⅱ）离子与它们是不等效的。每个Ni（Ⅱ）离子均为6配位[Ni1（Ⅱ）离子配位模式为N2 O4，Ni2（Ⅱ）和Ni2A（Ⅱ）离子配位模式为N3 O3]，配位构型均为畸变的八面体。配合物最终由氢键网联成具有2D结构的超分子。配合物的表面光电压光谱的测定结果表明，它在300～800 nm范围内呈现出正的表面光伏响应，表明它具有一定的光电转换能力。同时对配合物的UV-Vis-NIR吸收光谱和IR光谱进行了分析和指认。
